SUMMARY SECTION – US Treasury 30 Year Bond ETF

Investment Objective

The investment objective of the US Treasury 30 Year Bond ETF (the “UST 30 Year Bond Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA Current 30-Year US Treasury Index (GA30).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 30 Year Bond Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 30 Year Bond Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 30 Year Bond Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 30 Year Bond Fund for the time periods indicated and then 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 UST 30 Year Bond Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 30 Year Bond 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 UST 30 Year Bond 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 UST 30 Year Bond Fund’s performance. No portfolio turnover rate is provided for the UST 30 Year Bond Fund because the UST 30 Year Bond Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 30 Year Bond Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA Current 30-Year US Treasury Index (GA30) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 30 Year Bond Fund’s investment objective by investing at least 80% of the UST 30 Year Bond Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

1 

The Underlying Index

The Underlying Index was established December 31, 1987 by ICE Data Services (the “Index Provider”). The ICE BofA Current 30-Year US Treasury Index is a one-security index comprised of the most recently issued 30-year US Treasury bond. The index is rebalanced monthly. In order to qualify for inclusion, a 30-year bond must be auctioned on or before the third business day before the last business day of the month. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 30 Year Bond Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 30 Year Bond Fund’s investment strategy is to pursue its investment objective. The UST 30 Year Bond Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 30 Year Bond Fund track the Underlying Index.

The UST 30 Year Bond Fund has elected 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”).

Principal Investment Risks

The value of the UST 30 Year Bond Fund’s investments may decrease, which will cause the value of the UST 30 Year Bond Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 30 Year Bond Fund, and there can be no assurance that the UST 30 Year Bond Fund will achieve its investment objective. The UST 30 Year Bond 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 UST 30 Year Bond 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.

● Concentration Risk. The UST 30 Year Bond Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 30 Year Bond Fund’s investments more than the market as a whole, to the extent that the UST 30 Year Bond Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 30 Year Bond Fund’s assets, UST 30 Year Bond Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 30 Year Bond Fund, 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 the UST 30 Year Bond Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 30 Year Bond 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 UST 30 Year Bond Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 30 Year Bond Fund or its service providers may adversely impact and cause financial losses to the UST 30 Year Bond Fund or its shareholders. Issuers of securities in which the UST 30 Year Bond Fund invests are also subject to cyber security risks, and the value of these securities

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

2 

● ETF Risk. The UST 30 Year Bond 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. The UST 30 Year Bond 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, UST 30 Year Bond Fund 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 UST 30 Year Bond 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 UST 30 Year Bond 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 30 Year Bond 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 30 Year Bond Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 30 Year Bond Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 30 Year Bond Fund's share price and increase the UST 30 Year Bond Fund's liquidity risk, UST 30 Year Bond Fund expenses and/or taxable distributions.

● Income Risk. The UST 30 Year Bond Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 30 Year Bond Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 30 Year Bond Fund otherwise needs to purchase additional bonds.

3 

● Index Related Risk. There is no guarantee that the UST 30 Year Bond Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 30 Year Bond Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 30 Year Bond Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 30 Year Bond Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 30 Year Bond Fund receives from it but will generally affect the value of your investment in the UST 30 Year Bond Fund. Changes in interest rates may also affect the liquidity of the UST 30 Year Bond Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 30 Year Bond Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 30 Year Bond Fund’s performance will be negatively impacted. The UST 30 Year Bond Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 30 Year Bond Fund, resulting in a negative impact on the UST 30 Year Bond Fund's performance and NAV. Any interest rate increases could cause the value of the UST 30 Year Bond Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 30 Year Bond Fund, which may force the UST 30 Year Bond Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 30 Year Bond Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 30 Year Bond Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 30 Year Bond 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 UST 30 Year Bond Fund.

● Passive Investment Risk. The UST 30 Year Bond Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 30 Year Bond Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 30 Year Bond Fund generally does not attempt to invest the UST 30 Year Bond Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 30 Year Bond Fund's portfolio will decline if and when the UST 30 Year Bond Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

4 

● Tracking Error Risk. The UST 30 Year Bond Fund may be subject to tracking error, which is the divergence of the UST 30 Year Bond Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 30 Year Bond Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 30 Year Bond Fund, the UST 30 Year Bond Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 30 Year Bond Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 30 Year Bond Fund incurs fees and expenses, while the Underlying Index does not.

● 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.

Performance Information: Performance information for the UST 30 Year Bond Fund is not included because the UST 30 Year Bond Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the UST 30 Year Bond Fund has at least one calendar year of performance. Updated performance information will be available on the UST 30 Year Bond Fund’s website at www.ustreasuryetf.com.

Purchase and Sale of UST 30 Year Bond Fund Shares

Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (the “Exchange”), and investors can only buy and sell Shares through brokers or dealers 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). An investor 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, including information on the UST 30 Year Bond Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available on the UST 30 Year Bond Fund’s website at www.ustreasuryetf.com.

The UST 30 Year Bond 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 UST 30 Year Bond Fund generally issues and redeems Creation Units in exchange for a portfolio of securities closely approximating the holdings of the UST 30 Year Bond Fund (the “Deposit Securities”) and/or a designated amount of U.S. cash.

5 

Tax Information

UST 30 Year Bond Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is made through an individual retirement account (“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.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 30 Year Bond Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 30 Year Bond Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 30 Year Bond 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 UST 30 Year Bond Fund over another investment. Any such arrangements do not result in increased UST 30 Year Bond Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

SUMMARY SECTION – US Treasury 20 Year Bond ETF

Investment Objective

The investment objective of the US Treasury 20 Year Bond ETF (the “UST 20 Year Bond Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA Current 20-Year US Treasury Index (GA20).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 20 Year Bond Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 20 Year Bond Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 20 Year Bond Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 20 Year Bond Fund for the time periods indicated and then 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 UST 20 Year Bond Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 20 Year Bond 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 UST 20 Year Bond 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 UST 20 Year Bond Fund’s performance. No portfolio turnover rate is provided for the UST 20 Year Bond Fund because the UST 20 Year Bond Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 20 Year Bond Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA Current 20-Year US Treasury Index (GA20) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 20 Year Bond Fund’s investment objective by investing at least 80% of the UST 20 Year Bond Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

7 

The Underlying Index

The Underlying Index was established December 18, 1987 by ICE Data Services (the “Index Provider”). The ICE BofA Current 20-Year US Treasury Index is a one-security index comprised of the most recently issued 20-year US Treasury note. The index is rebalanced monthly. In order to qualify for inclusion, a 20-year note must be auctioned on or before the third business day before the last business day of the month. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 20 Year Bond Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 20 Year Bond Fund’s investment strategy is to pursue its investment objective. The UST 20 Year Bond Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 20 Year Bond Fund track the Underlying Index.

The UST 20 Year Bond Fund has elected 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”).

Principal Investment Risks

The value of the UST 20 Year Bond Fund’s investments may decrease, which will cause the value of the UST 20 Year Bond Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 20 Year Bond Fund, and there can be no assurance that the UST 20 Year Bond Fund will achieve its investment objective. The UST 20 Year Bond 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 UST 20 Year Bond 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.

● Concentration Risk. The UST 20 Year Bond Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 20 Year Bond Fund’s investments more than the market as a whole, to the extent that the UST 20 Year Bond Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 20 Year Bond Fund’s assets, UST 20 Year Bond Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 20 Year Bond Fund, 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 the UST 20 Year Bond Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 20 Year Bond 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 UST 20 Year Bond Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 20 Year Bond Fund or its service providers may adversely impact and cause financial losses to the UST 20 Year Bond Fund or its shareholders. Issuers of securities in which the UST 20 Year Bond 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.

8 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

● ETF Risk. The UST 20 Year Bond 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. The UST 20 Year Bond 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, UST 20 Year Bond Fund 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 UST 20 Year Bond 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 UST 20 Year Bond 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 20 Year Bond 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 20 Year Bond Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 20 Year Bond Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 20 Year Bond Fund's share price and increase the UST 20 Year Bond Fund's liquidity risk, UST 20 Year Bond Fund expenses and/or taxable distributions.

● Income Risk. The UST 20 Year Bond Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 20 Year Bond Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 20 Year Bond Fund otherwise needs to purchase additional bonds.

9 

● Index Related Risk. There is no guarantee that the UST 20 Year Bond Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 20 Year Bond Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 20 Year Bond Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 20 Year Bond Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 20 Year Bond Fund receives from it but will generally affect the value of your investment in the UST 20 Year Bond Fund. Changes in interest rates may also affect the liquidity of the UST 20 Year Bond Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 20 Year Bond Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 20 Year Bond Fund’s performance will be negatively impacted. The UST 20 Year Bond Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 20 Year Bond Fund, resulting in a negative impact on the UST 20 Year Bond Fund's performance and NAV. Any interest rate increases could cause the value of the UST 20 Year Bond Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 20 Year Bond Fund, which may force the UST 20 Year Bond Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 20 Year Bond Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 20 Year Bond Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 20 Year Bond 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 UST 20 Year Bond Fund.

● Passive Investment Risk. The UST 20 Year Bond Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 20 Year Bond Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 20 Year Bond Fund generally does not attempt to invest the UST 20 Year Bond Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 20 Year Bond Fund's portfolio will decline if and when the UST 20 Year Bond Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

10 

● Tracking Error Risk. The UST 20 Year Bond Fund may be subject to tracking error, which is the divergence of the UST 20 Year Bond Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 20 Year Bond Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 20 Year Bond Fund, the UST 20 Year Bond Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 20 Year Bond Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 20 Year Bond Fund incurs fees and expenses, while the Underlying Index does not.

● 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.

Performance Information: Performance information for the UST 20 Year Bond Fund is not included because the UST 20 Year Bond Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the UST 20 Year Bond Fund has at least one calendar year of performance. Updated performance information will be available on the UST 20 Year Bond Fund’s website at www.ustreasuryetf.com.

Purchase and Sale of UST 20 Year Bond Fund Shares

Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (the “Exchange”), and investors can only buy and sell Shares through brokers or dealers 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). An investor 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, including information on the UST 20 Year Bond Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available on the UST 20 Year Bond Fund’s website at www.ustreasuryetf.com.

The UST 20 Year Bond 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 UST 20 Year Bond Fund generally issues and redeems Creation Units in exchange for a portfolio of securities closely approximating the holdings of the UST 20 Year Bond Fund (the “Deposit Securities”) and/or a designated amount of U.S. cash.

11 

Tax Information

UST 20 Year Bond Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is made through an individual retirement account (“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.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 20 Year Bond Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 20 Year Bond Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 20 Year Bond 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 UST 20 Year Bond Fund over another investment. Any such arrangements do not result in increased UST 20 Year Bond Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

SUMMARY SECTION – US Treasury 10 Year Note ETF

Investment Objective

The investment objective of the US Treasury 10 Year Note ETF (the “UST 10 Year Note Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA Current 10-Year US Treasury Index (GA10).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 10 Year Note Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 10 Year Note Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 10 Year Note Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 10 Year Note Fund for the time periods indicated and then 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 UST 10 Year Note Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 10 Year Note 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 UST 10 Year Note 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 UST 10 Year Note Fund’s performance. No portfolio turnover rate is provided for the UST 10 Year Note Fund because the UST 10 Year Note Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 10 Year Note Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA Current 10-Year US Treasury Index (GA10) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 10 Year Note Fund’s investment objective by investing at least 80% of the UST 10 Year Note Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

13 

The Underlying Index

The Underlying Index was established December 31, 1987 by ICE Data Services (the “Index Provider”). The ICE BofA Current 10-Year US Treasury Index is a one-security index comprised of the most recently issued 10-year US Treasury note. The index is rebalanced monthly. In order to qualify for inclusion, a 10-year note must be auctioned on or before the third business day before the last business day of the month. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 10 Year Note Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 10 Year Note Fund’s investment strategy is to pursue its investment objective. The UST 10 Year Note Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 10 Year Note Fund track the Underlying Index.

The UST 10 Year Note Fund has elected 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”).

Principal Investment Risks

The value of the UST 10 Year Note Fund’s investments may decrease, which will cause the value of the UST 10 Year Note Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 10 Year Note Fund, and there can be no assurance that the UST 10 Year Note Fund will achieve its investment objective. The UST 10 Year Note 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 UST 10 Year Note 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.

● Concentration Risk. The UST 10 Year Note Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 10 Year Note Fund’s investments more than the market as a whole, to the extent that the UST 10 Year Note Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 10 Year Note Fund’s assets, UST 10 Year Note Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 10 Year Note Fund, 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 the UST 10 Year Note Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 10 Year Note 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 UST 10 Year Note Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 10 Year Note Fund or its service providers may adversely impact and cause financial losses to the UST 10 Year Note Fund or its shareholders. Issuers of securities in which the UST 10 Year Note 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.

14 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

● ETF Risk. The UST 10 Year Note 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. The UST 10 Year Note 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, UST 10 Year Note Fund 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 UST 10 Year Note 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 UST 10 Year Note 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 10 Year Note 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 10 Year Note Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 10 Year Note Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 10 Year Note Fund's share price and increase the UST 10 Year Note Fund's liquidity risk, UST 10 Year Note Fund expenses and/or taxable distributions.

● Income Risk. The UST 10 Year Note Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 10 Year Note Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 10 Year Note Fund otherwise needs to purchase additional bonds.

15 

● Index Related Risk. There is no guarantee that the UST 10 Year Note Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 10 Year Note Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 10 Year Note Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 10 Year Note Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 10 Year Note Fund receives from it but will generally affect the value of your investment in the UST 10 Year Note Fund. Changes in interest rates may also affect the liquidity of the UST 10 Year Note Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 10 Year Note Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 10 Year Note Fund’s performance will be negatively impacted. The UST 10 Year Note Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 10 Year Note Fund, resulting in a negative impact on the UST 10 Year Note Fund's performance and NAV. Any interest rate increases could cause the value of the UST 10 Year Note Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 10 Year Note Fund, which may force the UST 10 Year Note Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 10 Year Note Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 10 Year Note Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 10 Year Note 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 UST 10 Year Note Fund.

● Passive Investment Risk. The UST 10 Year Note Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 10 Year Note Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 10 Year Note Fund generally does not attempt to invest the UST 10 Year Note Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 10 Year Note Fund's portfolio will decline if and when the UST 10 Year Note Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

16 

● Tracking Error Risk. The UST 10 Year Note Fund may be subject to tracking error, which is the divergence of the UST 10 Year Note Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 10 Year Note Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 10 Year Note Fund, the UST 10 Year Note Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 10 Year Note Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 10 Year Note Fund incurs fees and expenses, while the Underlying Index does not.

● 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.

Performance Information: Performance information for the UST 10 Year Note Fund is not included because the UST 10 Year Note Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the UST 10 Year Note Fund has at least one calendar year of performance. Updated performance information will be available on the UST 10 Year Note Fund’s website at www.ustreasuryetf.com.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 10 Year Note Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 10 Year Note Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 10 Year Note 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 UST 10 Year Note Fund over another investment.

SUMMARY SECTION – US Treasury 7 Year Note ETF

Investment Objective

The investment objective of the US Treasury 7 Year Note ETF (the “UST 7 Year Note Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA Current 7-Year US Treasury Index (GA07).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 7 Year Note Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 7 Year Note Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 7 Year Note Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 7 Year Note Fund for the time periods indicated and then 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 UST 7 Year Note Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 7 Year Note 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 UST 7 Year Note 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 UST 7 Year Note Fund’s performance. No portfolio turnover rate is provided for the UST 7 Year Note Fund because the UST 7 Year Note Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 7 Year Note Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA Current 7-Year US Treasury Index (GA07) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 7 Year Note Fund’s investment objective by investing at least 80% of the UST 7 Year Note Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

The Underlying Index

The Underlying Index was established December 31, 1987 by ICE Data Services (the “Index Provider”). The ICE BofA Current 7-Year US Treasury Index is a one-security index comprised of the most recently issued 7-year US Treasury note. The index is rebalanced monthly. In order to qualify for inclusion, a 7-year note must be auctioned on or before the third business day before the last business day of the month. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 7 Year Note Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 7 Year Note Fund’s investment strategy is to pursue its investment objective. The UST 7 Year Note Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 7 Year Note Fund track the Underlying Index.

The UST 7 Year Note Fund has elected 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”).

Principal Investment Risks

The value of the UST 7 Year Note Fund’s investments may decrease, which will cause the value of the UST 7 Year Note Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 7 Year Note Fund, and there can be no assurance that the UST 7 Year Note Fund will achieve its investment objective. The UST 7 Year Note 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 UST 7 Year Note 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.

● Concentration Risk. The UST 7 Year Note Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 7 Year Note Fund’s investments more than the market as a whole, to the extent that the UST 7 Year Note Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 7 Year Note Fund’s assets, UST 7 Year Note Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 7 Year Note Fund, 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 the UST 7 Year Note Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 7 Year Note 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 UST 7 Year Note Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 7 Year Note Fund or its service providers may adversely impact and cause financial losses to the UST 7 Year Note Fund or its shareholders. Issuers of securities in which the UST 7 Year Note 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.

20 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

● ETF Risk. The UST 7 Year Note 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. The UST 7 Year Note 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, UST 7 Year Note Fund 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 UST 7 Year Note 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 UST 7 Year Note 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 7 Year Note 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 7 Year Note Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 7 Year Note Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 7 Year Note Fund's share price and increase the UST 7 Year Note Fund's liquidity risk, UST 7 Year Note Fund expenses and/or taxable distributions.

● Income Risk. The UST 7 Year Note Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 7 Year Note Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 7 Year Note Fund otherwise needs to purchase additional bonds.

21 

● Index Related Risk. There is no guarantee that the UST 7 Year Note Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 7 Year Note Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 7 Year Note Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 7 Year Note Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 7 Year Note Fund receives from it but will generally affect the value of your investment in the UST 7 Year Note Fund. Changes in interest rates may also affect the liquidity of the UST 7 Year Note Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 7 Year Note Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 7 Year Note Fund’s performance will be negatively impacted. The UST 7 Year Note Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 7 Year Note Fund, resulting in a negative impact on the UST 7 Year Note Fund's performance and NAV. Any interest rate increases could cause the value of the UST 7 Year Note Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 7 Year Note Fund, which may force the UST 7 Year Note Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 7 Year Note Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 7 Year Note Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 7 Year Note 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 UST 7 Year Note Fund.

● Passive Investment Risk. The UST 7 Year Note Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 7 Year Note Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 7 Year Note Fund generally does not attempt to invest the UST 7 Year Note Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 7 Year Note Fund's portfolio will decline if and when the UST 7 Year Note Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

22 

● Tracking Error Risk. The UST 7 Year Note Fund may be subject to tracking error, which is the divergence of the UST 7 Year Note Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 7 Year Note Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 7 Year Note Fund, the UST 7 Year Note Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 7 Year Note Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 7 Year Note Fund incurs fees and expenses, while the Underlying Index does not.

● 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.

Performance Information: Performance information for the UST 7 Year Note Fund is not included because the UST 7 Year Note Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the UST 7 Year Note Fund has at least one calendar year of performance. Updated performance information will be available on the UST 7 Year Note Fund’s website at www.ustreasuryetf.com.

Purchase and Sale of UST 7 Year Note Fund Shares

Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (the “Exchange”), and investors can only buy and sell Shares through brokers or dealers 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). An investor 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, including information on the UST 7 Year Note Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available on the UST 7 Year Note Fund’s website at www.ustreasuryetf.com.

The UST 7 Year Note 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 UST 7 Year Note Fund generally issues and redeems Creation Units in exchange for a portfolio of securities closely approximating the holdings of the UST 7 Year Note Fund (the “Deposit Securities”) and/or a designated amount of U.S. cash.

23 

Tax Information

UST 7 Year Note Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is made through an individual retirement account (“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.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 7 Year Note Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 7 Year Note Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 7 Year Note 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 UST 7 Year Note Fund over another investment. Any such arrangements do not result in increased UST 7 Year Note Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

SUMMARY SECTION – US Treasury 5 Year Note ETF

Investment Objective

The investment objective of the US Treasury 5 Year Note ETF (the “UST 5 Year Note Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA Current 5-Year US Treasury Index (GA05).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 5 Year Note Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 5 Year Note Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 5 Year Note Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 5 Year Note Fund for the time periods indicated and then 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 UST 5 Year Note Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 5 Year Note 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 UST 5 Year Note 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 UST 5 Year Note Fund’s performance. No portfolio turnover rate is provided for the UST 5 Year Note Fund because the UST 5 Year Note Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 5 Year Note Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA Current 5-Year US Treasury Index (GA05) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 5 Year Note Fund’s investment objective by investing at least 80% of the UST 5 Year Note Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

The Underlying Index

The Underlying Index was established December 31, 1987 by ICE Data Services (the “Index Provider”). The ICE BofA Current 5-Year US Treasury Index is a one-security index comprised of the most recently issued 5-year US Treasury note. The index is rebalanced monthly. In order to qualify for inclusion, a 5-year note must be auctioned on or before the third business day before the last business day of the month. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 5 Year Note Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 5 Year Note Fund’s investment strategy is to pursue its investment objective. The UST 5 Year Note Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 5 Year Note Fund track the Underlying Index.

The UST 5 Year Note Fund has elected 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”).

Principal Investment Risks

The value of the UST 5 Year Note Fund’s investments may decrease, which will cause the value of the UST 5 Year Note Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 5 Year Note Fund, and there can be no assurance that the UST 5 Year Note Fund will achieve its investment objective. The UST 5 Year Note 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 UST 5 Year Note 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.

● Concentration Risk. The UST 5 Year Note Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 5 Year Note Fund’s investments more than the market as a whole, to the extent that the UST 5 Year Note Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 5 Year Note Fund’s assets, UST 5 Year Note Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 5 Year Note Fund, 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 the UST 5 Year Note Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 5 Year Note 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 UST 5 Year Note Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 5 Year Note Fund or its service providers may adversely impact and cause financial losses to the UST 5 Year Note Fund or its shareholders. Issuers of securities in which the UST 5 Year Note 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.

26 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

● ETF Risk. The UST 5 Year Note 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. The UST 5 Year Note 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, UST 5 Year Note Fund 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 UST 5 Year Note 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 UST 5 Year Note 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 5 Year Note 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 5 Year Note Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 5 Year Note Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 5 Year Note Fund's share price and increase the UST 5 Year Note Fund's liquidity risk, UST 5 Year Note Fund expenses and/or taxable distributions.

● Income Risk. The UST 5 Year Note Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 5 Year Note Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 5 Year Note Fund otherwise needs to purchase additional bonds.

27 

● Index Related Risk. There is no guarantee that the UST 5 Year Note Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 5 Year Note Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 5 Year Note Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 5 Year Note Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 5 Year Note Fund receives from it but will generally affect the value of your investment in the UST 5 Year Note Fund. Changes in interest rates may also affect the liquidity of the UST 5 Year Note Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 5 Year Note Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 5 Year Note Fund’s performance will be negatively impacted. The UST 5 Year Note Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 5 Year Note Fund, resulting in a negative impact on the UST 5 Year Note Fund's performance and NAV. Any interest rate increases could cause the value of the UST 5 Year Note Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 5 Year Note Fund, which may force the UST 5 Year Note Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 5 Year Note Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 5 Year Note Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 5 Year Note 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 UST 5 Year Note Fund.

● Passive Investment Risk. The UST 5 Year Note Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 5 Year Note Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 5 Year Note Fund generally does not attempt to invest the UST 5 Year Note Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 5 Year Note Fund's portfolio will decline if and when the UST 5 Year Note Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

28 

● Tracking Error Risk. The UST 5 Year Note Fund may be subject to tracking error, which is the divergence of the UST 5 Year Note Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 5 Year Note Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 5 Year Note Fund, the UST 5 Year Note Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 5 Year Note Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 5 Year Note Fund incurs fees and expenses, while the Underlying Index does not.

● 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).

Purchase and Sale of UST 5 Year Note Fund Shares

Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (the “Exchange”), and investors can only buy and sell Shares through brokers or dealers 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). An investor 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, including information on the UST 5 Year Note Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available on the UST 5 Year Note Fund’s website at www.ustreasuryetf.com.

The UST 5 Year Note 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 UST 5 Year Note Fund generally issues and redeems Creation Units in exchange for a portfolio of securities closely approximating the holdings of the UST 5 Year Note Fund (the “Deposit Securities”) and/or a designated amount of U.S. cash.

Tax Information

UST 5 Year Note Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is made through an individual retirement account (“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.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 5 Year Note Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 5 Year Note Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 5 Year Note 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 UST 5 Year Note Fund over another investment. Any such arrangements do not result in increased UST 5 Year Note Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

SUMMARY SECTION – US Treasury 3 Year Note ETF

Investment Objective

The investment objective of the US Treasury 3 Year Note ETF (the “UST 3 Year Note Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA Current 3-Year US Treasury Index (GA03).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 3 Year Note Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 3 Year Note Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 3 Year Note Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 3 Year Note Fund for the time periods indicated and then 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 UST 3 Year Note Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 3 Year Note 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 UST 3 Year Note 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 UST 3 Year Note Fund’s performance. No portfolio turnover rate is provided for the UST 3 Year Note Fund because the UST 3 Year Note Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 3 Year Note Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA Current 3-Year US Treasury Index (GA03) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 3 Year Note Fund’s investment objective by investing at least 80% of the UST 3 Year Note Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

31 

The Underlying Index

The Underlying Index was established December 31, 1987 by ICE Data Services (the “Index Provider”). The ICE BofA Current 3-Year US Treasury Index is a one-security index comprised of the most recently issued 3-year US Treasury note. The index is rebalanced monthly. In order to qualify for inclusion, a 3-year note must be auctioned on or before the third business day before the last business day of the month. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 3 Year Note Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 3 Year Note Fund’s investment strategy is to pursue its investment objective. The UST 3 Year Note Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 3 Year Note Fund track the Underlying Index.

The UST 3 Year Note Fund has elected 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”).

Principal Investment Risks

The value of the UST 3 Year Note Fund’s investments may decrease, which will cause the value of the UST 3 Year Note Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 3 Year Note Fund, and there can be no assurance that the UST 3 Year Note Fund will achieve its investment objective. The UST 3 Year Note 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 UST 3 Year Note 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.

● Concentration Risk. The UST 3 Year Note Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 3 Year Note Fund’s investments more than the market as a whole, to the extent that the UST 3 Year Note Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 3 Year Note Fund’s assets, UST 3 Year Note Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 3 Year Note Fund, 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 the UST 3 Year Note Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 3 Year Note 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 UST 3 Year Note Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 3 Year Note Fund or its service providers may adversely impact and cause financial losses to the UST 3 Year Note Fund or its shareholders. Issuers of securities in which the UST 3 Year Note 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.

32 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

● ETF Risk. The UST 3 Year Note 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. The UST 3 Year Note 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, UST 3 Year Note Fund 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 UST 3 Year Note 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 UST 3 Year Note 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 3 Year Note 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 3 Year Note Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 3 Year Note Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 3 Year Note Fund's share price and increase the UST 3 Year Note Fund's liquidity risk, UST 3 Year Note Fund expenses and/or taxable distributions.

● Income Risk. The UST 3 Year Note Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 3 Year Note Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 3 Year Note Fund otherwise needs to purchase additional bonds.

33 

● Index Related Risk. There is no guarantee that the UST 3 Year Note Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 3 Year Note Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 3 Year Note Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 3 Year Note Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 3 Year Note Fund receives from it but will generally affect the value of your investment in the UST 3 Year Note Fund. Changes in interest rates may also affect the liquidity of the UST 3 Year Note Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 3 Year Note Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 3 Year Note Fund’s performance will be negatively impacted. The UST 3 Year Note Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 3 Year Note Fund, resulting in a negative impact on the UST 3 Year Note Fund's performance and NAV. Any interest rate increases could cause the value of the UST 3 Year Note Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 3 Year Note Fund, which may force the UST 3 Year Note Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 3 Year Note Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 3 Year Note Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 3 Year Note 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 UST 3 Year Note Fund.

● Passive Investment Risk. The UST 3 Year Note Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 3 Year Note Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 3 Year Note Fund generally does not attempt to invest the UST 3 Year Note Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 3 Year Note Fund's portfolio will decline if and when the UST 3 Year Note Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

34 

● Tracking Error Risk. The UST 3 Year Note Fund may be subject to tracking error, which is the divergence of the UST 3 Year Note Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 3 Year Note Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 3 Year Note Fund, the UST 3 Year Note Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 3 Year Note Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 3 Year Note Fund incurs fees and expenses, while the Underlying Index does not.

● 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.

Performance Information: Performance information for the UST 3 Year Note Fund is not included because the UST 3 Year Note Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the UST 3 Year Note Fund has at least one calendar year of performance. Updated performance information will be available on the UST 3 Year Note Fund’s website at www.ustreasuryetf.com.

Purchase and Sale of UST 3 Year Note Fund Shares

Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (the “Exchange”), and investors can only buy and sell Shares through brokers or dealers 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). An investor 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, including information on the UST 3 Year Note Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available on the UST 3 Year Note Fund’s website at www.ustreasuryetf.com.

The UST 3 Year Note 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 UST 3 Year Note Fund generally issues and redeems Creation Units in exchange for a portfolio of securities closely approximating the holdings of the UST 3 Year Note Fund (the “Deposit Securities”) and/or a designated amount of U.S. cash.

35 

Tax Information

UST 3 Year Note Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is made through an individual retirement account (“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.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 3 Year Note Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 3 Year Note Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 3 Year Note 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 UST 3 Year Note Fund over another investment. Any such arrangements do not result in increased UST 3 Year Note Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

SUMMARY SECTION – US Treasury 2 Year Note ETF

Investment Objective

The investment objective of the US Treasury 2 Year Note ETF (the “UST 2 Year Note Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA Current 2-Year US Treasury Index (GA02).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 2 Year Note Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 2 Year Note Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 2 Year Note Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 2 Year Note Fund for the time periods indicated and then 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 UST 2 Year Note Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 2 Year Note 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 UST 2 Year Note 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 UST 2 Year Note Fund’s performance. No portfolio turnover rate is provided for the UST 2 Year Note Fund because the UST 2 Year Note Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 2 Year Note Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA Current 2-Year US Treasury Index (GA02) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 2 Year Note Fund’s investment objective by investing at least 80% of the UST 2 Year Note Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

37 

The Underlying Index

The Underlying Index was established December 31, 1987 by ICE Data Services (the “Index Provider”). The ICE BofA Current 2-Year US Treasury Index is a one-security index comprised of the most recently issued 2-year US Treasury note. The index is rebalanced monthly. In order to qualify for inclusion, a 2-year note must be auctioned on or before the third business day before the last business day of the month. The Underlying Index may be comprised of only one or two U.S. Treasury securities at a given time. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 2 Year Note Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 2 Year Note Fund’s investment strategy is to pursue its investment objective. The UST 2 Year Note Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 2 Year Note Fund track the Underlying Index.

The UST 2 Year Note Fund has elected 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”).

Principal Investment Risks

The value of the UST 2 Year Note Fund’s investments may decrease, which will cause the value of the UST 2 Year Note Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 2 Year Note Fund, and there can be no assurance that the UST 2 Year Note Fund will achieve its investment objective. The UST 2 Year Note 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 UST 2 Year Note 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.

● Concentration Risk. The UST 2 Year Note Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 2 Year Note Fund’s investments more than the market as a whole, to the extent that the UST 2 Year Note Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 2 Year Note Fund’s assets, UST 2 Year Note Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 2 Year Note Fund, 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 the UST 2 Year Note Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 2 Year Note 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 UST 2 Year Note Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 2 Year Note Fund or its service providers may adversely impact and cause financial losses to the UST 2 Year Note Fund or its shareholders. Issuers of securities in which the UST 2 Year Note 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.

38 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

● ETF Risk. The UST 2 Year Note 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. The UST 2 Year Note 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, UST 2 Year Note Fund 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 UST 2 Year Note 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 UST 2 Year Note 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 2 Year Note 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 2 Year Note Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 2 Year Note Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 2 Year Note Fund's share price and increase the UST 2 Year Note Fund's liquidity risk, UST 2 Year Note Fund expenses and/or taxable distributions.

● Income Risk. The UST 2 Year Note Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 2 Year Note Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 2 Year Note Fund otherwise needs to purchase additional bonds.

39 

● Index Related Risk. There is no guarantee that the UST 2 Year Note Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 2 Year Note Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 2 Year Note Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 2 Year Note Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 2 Year Note Fund receives from it but will generally affect the value of your investment in the UST 2 Year Note Fund. Changes in interest rates may also affect the liquidity of the UST 2 Year Note Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 2 Year Note Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 2 Year Note Fund’s performance will be negatively impacted. The UST 2 Year Note Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 2 Year Note Fund, resulting in a negative impact on the UST 2 Year Note Fund's performance and NAV. Any interest rate increases could cause the value of the UST 2 Year Note Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 2 Year Note Fund, which may force the UST 2 Year Note Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 2 Year Note Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 2 Year Note Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 2 Year Note 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 UST 2 Year Note Fund.

● Passive Investment Risk. The UST 2 Year Note Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 2 Year Note Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 2 Year Note Fund generally does not attempt to invest the UST 2 Year Note Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 2 Year Note Fund's portfolio will decline if and when the UST 2 Year Note Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

40 

● Tracking Error Risk. The UST 2 Year Note Fund may be subject to tracking error, which is the divergence of the UST 2 Year Note Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 2 Year Note Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 2 Year Note Fund, the UST 2 Year Note Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 2 Year Note Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 2 Year Note Fund incurs fees and expenses, while the Underlying Index does not.

● 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.

Performance Information: Performance information for the UST 2 Year Note Fund is not included because the UST 2 Year Note Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the UST 2 Year Note Fund has at least one calendar year of performance. Updated performance information will be available on the UST 2 Year Note Fund’s website at www.ustreasuryetf.com.

Purchase and Sale of UST 2 Year Note Fund Shares

Shares are listed on a national securities exchange, the Exchange, and investors can only buy and sell Shares through brokers or dealers 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). An investor 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, including information on the UST 2 Year Note Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available on the UST 2 Year Note Fund’s website at www.ustreasuryetf.com.

The UST 2 Year Note 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 UST 2 Year Note Fund generally issues and redeems Creation Units in exchange for a portfolio of securities closely approximating the holdings of the UST 2 Year Note Fund (the “Deposit Securities”) and/or a designated amount of U.S. cash.

41 

Tax Information

UST 2 Year Note Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is made through an individual retirement account (“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.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 2 Year Note Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 2 Year Note Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 2 Year Note 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 UST 2 Year Note Fund over another investment. Any such arrangements do not result in increased UST 2 Year Note Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

SUMMARY SECTION – US Treasury 12 Month Bill ETF

Investment Objective

The investment objective of the US Treasury 12 Month Bill ETF (the “UST 12 Month Bill Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA US 1-Year Treasury Bill Index (G0O3).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 12 Month Bill Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 12 Month Bill Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 12 Month Bill Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 12 Month Bill Fund for the time periods indicated and then 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 UST 12 Month Bill Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 12 Month Bill 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 UST 12 Month Bill 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 UST 12 Month Bill Fund’s performance. No portfolio turnover rate is provided for the UST 12 Month Bill Fund because the UST 12 Month Bill Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 12 Month Bill Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA US 1-Year Treasury Bill Index (G0O3) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 12 Month Bill Fund’s investment objective by investing at least 80% of the UST 12 Month Bill Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

43 

The Underlying Index

The Underlying Index was established May 31, 1991 by ICE Data Services (the “Index Provider”). The Underlying Index is comprised of a single issue purchased at the beginning of the month and held for a full month. At the end of the month that issue is sold and rolled into a newly selected issue. The issue selected at each month-end rebalancing is the outstanding Treasury Bill that matures closest to, but not beyond, 1 year from the rebalancing date. To qualify for selection, an issue must have settled on or before the month-end rebalancing date. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 12 Month Bill Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 12 Month Bill Fund’s investment strategy is to pursue its investment objective. The UST 12 Month Bill Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 12 Month Bill Fund track the Underlying Index.

The UST 12 Month Bill Fund has elected 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”).

Principal Investment Risks

The value of the UST 12 Month Bill Fund’s investments may decrease, which will cause the value of the UST 12 Month Bill Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 12 Month Bill Fund, and there can be no assurance that the UST 12 Month Bill Fund will achieve its investment objective. The UST 12 Month Bill 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 UST 12 Month Bill 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.

● Concentration Risk. The UST 12 Month Bill Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 12 Month Bill Fund’s investments more than the market as a whole, to the extent that the UST 12 Month Bill Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 12 Month Bill Fund’s assets, UST 12 Month Bill Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 12 Month Bill Fund, 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 the UST 12 Month Bill Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 12 Month Bill 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 UST 12 Month Bill Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 12 Month Bill Fund or its service providers may adversely impact and cause financial losses to the UST 12 Month Bill Fund or its shareholders. Issuers of securities in which the UST 12 Month Bill 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.

44 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

● ETF Risk. The UST 12 Month Bill 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. The UST 12 Month Bill 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, UST 12 Month Bill Fund 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 UST 12 Month Bill 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 UST 12 Month Bill 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 12 Month Bill 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 12 Month Bill Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 12 Month Bill Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 12 Month Bill Fund's share price and increase the UST 12 Month Bill Fund's liquidity risk, UST 12 Month Bill Fund expenses and/or taxable distributions.

● Income Risk. The UST 12 Month Bill Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 12 Month Bill Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 12 Month Bill Fund otherwise needs to purchase additional bonds.

45 

● Index Related Risk. There is no guarantee that the UST 12 Month Bill Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 12 Month Bill Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 12 Month Bill Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 12 Month Bill Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 12 Month Bill Fund receives from it but will generally affect the value of your investment in the UST 12 Month Bill Fund. Changes in interest rates may also affect the liquidity of the UST 12 Month Bill Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 12 Month Bill Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 12 Month Bill Fund’s performance will be negatively impacted. The UST 12 Month Bill Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 12 Month Bill Fund, resulting in a negative impact on the UST 12 Month Bill Fund's performance and NAV. Any interest rate increases could cause the value of the UST 12 Month Bill Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 12 Month Bill Fund, which may force the UST 12 Month Bill Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 12 Month Bill Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 12 Month Bill Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 12 Month Bill 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 UST 12 Month Bill Fund.

● Passive Investment Risk. The UST 12 Month Bill Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 12 Month Bill Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 12 Month Bill Fund generally does not attempt to invest the UST 12 Month Bill Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 12 Month Bill Fund's portfolio will decline if and when the UST 12 Month Bill Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

46 

● Tracking Error Risk. The UST 12 Month Bill Fund may be subject to tracking error, which is the divergence of the UST 12 Month Bill Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 12 Month Bill Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 12 Month Bill Fund, the UST 12 Month Bill Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 12 Month Bill Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 12 Month Bill Fund incurs fees and expenses, while the Underlying Index does not.

● 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.

Performance Information: Performance information for the UST 12 Month Bill Fund is not included because the UST 12 Month Bill Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the UST 12 Month Bill Fund has at least one calendar year of performance. Updated performance information will be available on the UST 12 Month Bill Fund’s website at www.ustreasuryetf.com.

Tax Information

UST 12 Month Bill Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is made through an individual retirement account (“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.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 12 Month Bill Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 12 Month Bill Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 12 Month Bill 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 UST 12 Month Bill Fund over another investment. Any such arrangements do not result in increased UST 12 Month Bill Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

SUMMARY SECTION – US Treasury 6 Month Bill ETF

Investment Objective

The investment objective of the US Treasury 6 Month Bill ETF (the “UST 6 Month Bill Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA US 6-Month Treasury Bill Index (G0O2).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 6 Month Bill Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 6 Month Bill Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 6 Month Bill Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 6 Month Bill Fund for the time periods indicated and then 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 UST 6 Month Bill Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 6 Month Bill 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 UST 6 Month Bill 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 UST 6 Month Bill Fund’s performance. No portfolio turnover rate is provided for the UST 6 Month Bill Fund because the UST 6 Month Bill Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 6 Month Bill Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA US 6-Month Treasury Bill Index (G0O2) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 6 Month Bill Fund’s investment objective by investing at least 80% of the UST 6 Month Bill Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

49 

The Underlying Index

The Underlying Index was established December 31, 1977 by ICE Data Services (the “Index Provider”). The Underlying Index is comprised of a single issue purchased at the beginning of the month and held for a full month. At the end of the month that issue is sold and rolled into a newly selected issue. The issue selected at each month-end rebalancing is the outstanding Treasury Bill that matures closest to, but not beyond, six months from the rebalancing date. To qualify for selection, an issue must have settled on or before the month-end rebalancing date. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 6 Month Bill Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 6 Month Bill Fund’s investment strategy is to pursue its investment objective. The UST 6 Month Bill Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 6 Month Bill Fund track the Underlying Index.

The UST 6 Month Bill Fund has elected 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”).

Principal Investment Risks

The value of the UST 6 Month Bill Fund’s investments may decrease, which will cause the value of the UST 6 Month Bill Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 6 Month Bill Fund, and there can be no assurance that the UST 6 Month Bill Fund will achieve its investment objective. The UST 6 Month Bill 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 UST 6 Month Bill 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.

● Concentration Risk. The UST 6 Month Bill Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 6 Month Bill Fund’s investments more than the market as a whole, to the extent that the UST 6 Month Bill Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 6 Month Bill Fund’s assets, UST 6 Month Bill Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 6 Month Bill Fund, 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 the UST 6 Month Bill Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 6 Month Bill 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 UST 6 Month Bill Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 6 Month Bill Fund or its service providers may adversely impact and cause financial losses to the UST 6 Month Bill Fund or its shareholders. Issuers of securities in which the UST 6 Month Bill 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.

50 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

● ETF Risk. The UST 6 Month Bill 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. The UST 6 Month Bill 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, UST 6 Month Bill Fund 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 UST 6 Month Bill 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 UST 6 Month Bill 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 6 Month Bill 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 6 Month Bill Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 6 Month Bill Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 6 Month Bill Fund's share price and increase the UST 6 Month Bill Fund's liquidity risk, UST 6 Month Bill Fund expenses and/or taxable distributions.

● Income Risk. The UST 6 Month Bill Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 6 Month Bill Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 6 Month Bill Fund otherwise needs to purchase additional bonds.

51 

● Index Related Risk. There is no guarantee that the UST 6 Month Bill Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 6 Month Bill Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 6 Month Bill Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 6 Month Bill Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 6 Month Bill Fund receives from it but will generally affect the value of your investment in the UST 6 Month Bill Fund. Changes in interest rates may also affect the liquidity of the UST 6 Month Bill Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 6 Month Bill Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 6 Month Bill Fund’s performance will be negatively impacted. The UST 6 Month Bill Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 6 Month Bill Fund, resulting in a negative impact on the UST 6 Month Bill Fund's performance and NAV. Any interest rate increases could cause the value of the UST 6 Month Bill Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 6 Month Bill Fund, which may force the UST 6 Month Bill Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 6 Month Bill Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 6 Month Bill Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 6 Month Bill 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 UST 6 Month Bill Fund.

● Passive Investment Risk. The UST 6 Month Bill Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 6 Month Bill Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 6 Month Bill Fund generally does not attempt to invest the UST 6 Month Bill Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 6 Month Bill Fund's portfolio will decline if and when the UST 6 Month Bill Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

52 

● Tracking Error Risk. The UST 6 Month Bill Fund may be subject to tracking error, which is the divergence of the UST 6 Month Bill Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 6 Month Bill Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 6 Month Bill Fund, the UST 6 Month Bill Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 6 Month Bill Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 6 Month Bill Fund incurs fees and expenses, while the Underlying Index does not.

● 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.

Performance Information: Performance information for the UST 6 Month Bill Fund is not included because the UST 6 Month Bill Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the UST 6 Month Bill Fund has at least one calendar year of performance. Updated performance information will be available on the UST 6 Month Bill Fund’s website at www.ustreasuryetf.com.

Purchase and Sale of UST 6 Month Bill Fund Shares

Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (the “Exchange”), and investors can only buy and sell Shares through brokers or dealers 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). An investor 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, including information on the UST 6 Month Bill Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available on the UST 6 Month Bill Fund’s website at www.ustreasuryetf.com.

The UST 6 Month Bill 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 UST 6 Month Bill Fund generally issues and redeems Creation Units in exchange for a portfolio of securities closely approximating the holdings of the UST 6 Month Bill Fund (the “Deposit Securities”) and/or a designated amount of U.S. cash.

53 

Tax Information

UST 6 Month Bill Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is made through an individual retirement account (“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.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 6 Month Bill Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 6 Month Bill Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 6 Month Bill 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 UST 6 Month Bill Fund over another investment. Any such arrangements do not result in increased UST 6 Month Bill Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

SUMMARY SECTION – US Treasury 3 Month Bill ETF

Investment Objective

The investment objective of the US Treasury 3 Month Bill ETF (the “UST 3 Month Bill Fund”) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the ICE BofA US 3-Month Treasury Bill Index (G0O1).

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the UST 3 Month Bill Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of UST 3 Month Bill Fund Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):
Management Fees	0.15 %
Distribution (12b-1) Fees	None
Other Expenses	None %
Total Annual Fund Operating Expenses	0.15 %

Example

This Example is intended to help you compare the cost of investing in the UST 3 Month Bill Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the UST 3 Month Bill Fund for the time periods indicated and then 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 UST 3 Month Bill Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$15	$48

Portfolio Turnover

The UST 3 Month Bill 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 UST 3 Month Bill 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 UST 3 Month Bill Fund’s performance. No portfolio turnover rate is provided for the UST 3 Month Bill Fund because the UST 3 Month Bill Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The UST 3 Month Bill Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA US 3-Month Treasury Bill Index (G0O1) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 3 Month Bill Fund’s investment objective by investing at least 80% of the UST 3 Month Bill Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index.

55 

The Underlying Index

The Underlying Index was established December 31, 1977 by ICE Data Services (the “Index Provider”). The Underlying Index is comprised of a single issue purchased at the beginning of the month and held for a full month. At the end of the month that issue is sold and rolled into a newly selected issue. The issue selected at each month-end rebalancing is the outstanding Treasury Bill that matures closest to, but not beyond, three months from the rebalancing date. To qualify for selection, an issue must have settled on or before the month-end rebalancing date. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities). This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 3 Month Bill Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 3 Month Bill Fund’s investment strategy is to pursue its investment objective. The UST 3 Month Bill Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 3 Month Bill Fund track the Underlying Index.

The UST 3 Month Bill Fund has elected 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”).

Principal Investment Risks

The value of the UST 3 Month Bill Fund’s investments may decrease, which will cause the value of the UST 3 Month Bill Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 3 Month Bill Fund, and there can be no assurance that the UST 3 Month Bill Fund will achieve its investment objective. The UST 3 Month Bill 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 UST 3 Month Bill 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.

● Concentration Risk. The UST 3 Month Bill Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 3 Month Bill Fund’s investments more than the market as a whole, to the extent that the UST 3 Month Bill Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 3 Month Bill Fund’s assets, UST 3 Month Bill Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 3 Month Bill Fund, 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 the UST 3 Month Bill Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 3 Month Bill 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 UST 3 Month Bill Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 3 Month Bill Fund or its service providers may adversely impact and cause financial losses to the UST 3 Month Bill Fund or its shareholders. Issuers of securities in which the UST 3 Month Bill 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.

56 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

● ETF Risk. The UST 3 Month Bill 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. The UST 3 Month Bill 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, UST 3 Month Bill Fund 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 UST 3 Month Bill 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 UST 3 Month Bill 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.

● Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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. 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 it is expected that the market price of Shares will approximate the UST 3 Month Bill 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). This risk is heightened in times of market volatility or periods of steep market declines.

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. An unexpected increase in UST 3 Month Bill Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 3 Month Bill Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 3 Month Bill Fund's share price and increase the UST 3 Month Bill Fund's liquidity risk, UST 3 Month Bill Fund expenses and/or taxable distributions.

● Income Risk. The UST 3 Month Bill Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 3 Month Bill Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 3 Month Bill Fund otherwise needs to purchase additional bonds.

57 

● Index Related Risk. There is no guarantee that the UST 3 Month Bill Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 3 Month Bill Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 3 Month Bill Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 3 Month Bill Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 3 Month Bill Fund receives from it but will generally affect the value of your investment in the UST 3 Month Bill Fund. Changes in interest rates may also affect the liquidity of the UST 3 Month Bill Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 3 Month Bill Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 3 Month Bill Fund’s performance will be negatively impacted. The UST 3 Month Bill Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 3 Month Bill Fund, resulting in a negative impact on the UST 3 Month Bill Fund's performance and NAV. Any interest rate increases could cause the value of the UST 3 Month Bill Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 3 Month Bill Fund, which may force the UST 3 Month Bill Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 3 Month Bill Fund’s NAV and market price may fluctuate significantly in response to these and other factors including 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. As a result, an investor could lose money over short or long periods of time.

● New Fund Risk. The UST 3 Month Bill Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 3 Month Bill 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 UST 3 Month Bill Fund.

● Passive Investment Risk. The UST 3 Month Bill Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 3 Month Bill Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 3 Month Bill Fund generally does not attempt to invest the UST 3 Month Bill Fund's assets in defensive positions under any market conditions, including declining markets.

● Reinvestment Risk. Reinvestment risk is the risk that income from the UST 3 Month Bill Fund's portfolio will decline if and when the UST 3 Month Bill Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of the Shares.

58 

● Tracking Error Risk. The UST 3 Month Bill Fund may be subject to tracking error, which is the divergence of the UST 3 Month Bill Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 3 Month Bill Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 3 Month Bill Fund, the UST 3 Month Bill Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 3 Month Bill Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 3 Month Bill Fund incurs fees and expenses, while the Underlying Index does not.

● 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.

Purchase and Sale of UST 3 Month Bill Fund Shares

Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (the “Exchange”), and investors can only buy and sell Shares through brokers or dealers 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).

Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the UST 3 Month Bill Fund’s investment adviser or its affiliates may pay Intermediaries for certain activities related to the UST 3 Month Bill Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the UST 3 Month Bill 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 UST 3 Month Bill Fund over another investment.

Additional Principal Risk Information

The value of the Funds’ investments may decrease, which will cause the value of the Fund’s Shares to decrease. As a result, you may lose money on your investment in any of the Funds, and there can be no assurance that any of the Funds will achieve its investment objective. An investment in the Funds is subject to one or more of the principal risks discussed below.

● Concentration Risk. Any of the Funds may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

● Cyber Security Risk. With the increased use of technologies such as the internet to conduct business, any of the Fund is susceptible to operational, information security and related risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber-attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through "hacking" or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber-attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures or breaches by the Adviser and other service providers (including, but not limited to, any of the Funds’ accountant, custodian, transfer agent and administrator), and the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with any of the Funds’ ability to calculate its NAV, impediments to trading, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. While the Adviser has established business continuity plans in the event of, and risk management systems to prevent, such cyber-attacks, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Funds cannot control the cyber security plans and systems put in place by service providers to the Funds and issuers in which the Funds invest. The Funds and their shareholders could be negatively impacted as a result.

61 

● Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities are more volatile and thus more likely to decline in price, and to a greater extent, than shorter-duration debt securities, in a rising interest-rate environment. “Effective duration” attempts to measure the expected percentage change in the value of a bond or portfolio resulting from a change in prevailing interest rates. The change in the value of a bond or portfolio can be approximated by multiplying its duration by a change in interest rates. For example, if a bond has an effective duration of three years, a 1% increase in general interest rates would be expected to cause the bond’s value to decline about 3% while a 1% decrease in general interest rates would be expected to cause the bond’s value to increase 3%. The duration of a debt security may be equal to or shorter than the full maturity of a debt security.

● ETF Risk. Each of the Funds is an ETF, and, as a result of an ETF's structure, the Funds are exposed to the following risks:

● Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Each Fund may have a limited number of financial institutions that 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 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 a Fund’s Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of any of the Funds 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.

● Secondary Market Trading Risk. Although the Funds’ Shares are listed for trading on Nasdaq Stock Market, LLC (the “Exchange”) and may be listed or traded on U.S. and non-U.S. stock exchanges other than the Exchange, there can be no assurance that an active trading market for Shares will develop or be maintained. Trading in the Funds’ Shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to Exchange “circuit breaker” rules, which temporarily halt trading on the Exchange. Additional rules applicable to the Exchange may halt trading in Shares when extraordinary volatility causes sudden, significant swings in the market price of Shares. There can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of the Funds’ Shares may begin to mirror the liquidity of each Fund’s underlying holdings, which can be significantly less liquid than each Fund’s Shares. In addition, 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 of the Funds may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate each 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 or periods of steep market declines. The market price of Shares during the trading day, like the price of any exchange-traded security, includes a “bid/ask” spread charged by the exchange specialist, market makers or other participants that trade Shares. In times of severe market disruption, the bid/ask spread can increase significantly. At those times, Shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of Shares is falling fastest, which may be the time that you most want to sell your Shares. The Adviser believes that, under normal market conditions, large market price discounts or premiums to NAV will not be sustained because of arbitrage opportunities.

62 

● Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates), which currently are at or near historic lows in the United States and in other countries. During periods of reduced market liquidity, any of the Funds may not be able to readily sell fixed-income securities at prices at or near their perceived value. If a Fund needed to sell large blocks of fixed-income securities to meet shareholder redemption requests or to raise cash, those sales could further reduce the prices of such securities. An unexpected increase in a Fund’s redemption requests, including requests from shareholders who may own a significant percentage of a Fund's Shares, which may be triggered by market turmoil or an increase in interest rates, could cause a Fund to sell its holdings at a loss or at undesirable prices and adversely affect that Fund's share price and increase that Fund's liquidity risk, fund expenses and/or taxable distributions. Economic and other market developments can adversely affect fixed-income securities markets. Regulations and business practices, for example, have led some financial intermediaries to curtail their capacity to engage in trading (i.e., "market making") activities for certain fixed-income securities, which could have the potential to decrease liquidity and increase volatility in the fixed-income securities markets. Policy and legislative changes worldwide are affecting many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.

● Income Risk. The Funds’ income may decline if interest rates fall. This decline in income can occur because the Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the Fund otherwise needs to purchase additional bonds.

● Index Related Risk. The Funds seeks to achieve a return that corresponds generally to the price and yield performance, before fees and expenses, of each Fund’s Underlying Index as published by the sponsor (ICE Data Services or the “Index Provider”). There is no assurance that the Index Provider or any agents that may act on its behalf will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what each Underlying Index is designed to achieve, neither the Index Provider nor its agents provide any warranty or accept any liability in relation to the quality, accuracy or completeness of the Underlying Indices or its related data, and they do not guarantee that the Underlying Indices will be in line with the Index Provider’s methodology. The Funds’ strategies as described in this Prospectus are to manage each Fund consistently with that Fund’s Underlying Index. The Funds do not provide any warranty or guarantee against the Index Provider’s or any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Such errors may negatively or positively impact the Funds and their shareholders. For example, during a period where an Underlying Index contains incorrect constituents, the corresponding Fund would have market exposure to such constituents and would be underexposed to that Underlying Index’s other constituents. Shareholders should understand that any gains from Index Provider errors will be kept by corresponding Fund and its shareholders and any losses or costs resulting from Index Provider errors will be borne by the corresponding Fund and its shareholders.

63 

Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance to an Underlying Index, which could cause that Underlying Index to vary from its normal or expected composition. The postponement of a scheduled rebalance in a time of market volatility could mean that constituents of that Underlying Index that would otherwise be removed at rebalance due to changes in market value, issuer credit ratings, or other reasons may remain, causing the performance and constituents of that Underlying Index to vary from those expected under normal conditions. Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Underlying Indices due to reaching certain weighting constraints, unusual market conditions or corporate events or, for example, to correct an error in the selection of index constituents. When an Underlying Index is rebalanced and the corresponding Fund in turn rebalances its portfolio to attempt to increase the correlation between that Fund’s portfolio and its Underlying Index, any transaction costs and market exposure arising from such portfolio rebalancing will be borne directly by that Fund and its shareholders. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Indices may increase the costs to and the tracking error risk of the Fund.

● Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Funds receive from it but will generally affect the value of your investment in the Funds. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Funds’ yield(s) and may increase the risk that, if followed by rising interest rates, the Funds’ performance will be negatively impacted. The Funds are subject to the risk that the income generated by their investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Funds, resulting in a negative impact on the Funds’ performance and NAV. Any interest rate increases could cause the value of the Funds’ investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

● Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors including 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. The Funds’ NAVs and market prices are based upon the market’s perception of value and is not necessarily an objective measure of an investment’s value. There is no assurance that any of the Funds will realize its investment objective, and an investment in any of the Funds is not, by itself, a complete or balanced investment program. You could lose money on your investment in any of the Funds, or any of the Funds could underperform other investments.

Periods of unusually high financial market volatility and restrictive credit conditions, at times limited to a particular sector or geographic area, have occurred in the past and may be expected to recur in the future. Some countries, including the United States, have adopted or have signaled protectionist trade measures, relaxation of the financial industry regulations that followed the financial crisis, and/or reductions to corporate taxes. The scope of these policy changes is still developing, but the equity and debt markets may react strongly to expectations of change, which could increase volatility, particularly if a resulting policy runs counter to the market’s expectations. The outcome of such changes cannot be foreseen at the present time. In addition, geopolitical and other risks, including environmental and public health risks, may add to instability in the world economy and markets generally. As a result of increasingly interconnected global economies and financial markets, the value and liquidity of the Funds’ investments may be negatively affected by events impacting a country or region, regardless of whether any of the Funds invests in issuers located in or with significant exposure to such country or region.

64 

The continuing spread of an infectious respiratory illness caused by a novel strain of coronavirus (known as COVID-19) has caused volatility, severe market dislocations and liquidity constraints in many markets and may adversely affect the Fund’s investments and operations. The outbreak was first detected in December 2019 and subsequently spread globally. The transmission of COVID-19 and efforts to contain its spread have resulted in international and domestic travel restrictions and disruptions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, quarantines, event and service cancellations or interruptions, disruptions to business operations (including staff reductions), supply chains and consumer activity, as well as general concern and uncertainty that has negatively affected the economic environment. These disruptions have led to instability in the marketplace, including stock and credit market losses and overall volatility. The impact of COVID-19, and other infectious illness outbreaks, epidemics or pandemics that may arise in the future, could adversely affect the economies of many nations or the entire global economy, the financial performance of individual issuers, borrowers and sectors and the health of the markets generally in potentially significant and unforeseen ways. Health crises caused by the recent outbreak may heighten other pre-existing political, social and economic risks in a country or region. In the event of a pandemic or an outbreak, there can be no assurance that the Funds and their service providers will be able to maintain normal business operations for an extended period of time or will not lose the services of key personnel on a temporary or long-term basis due to illness or other reasons. Although vaccines for COVID-19 are becoming more widely available, the full impacts of a pandemic or disease outbreaks are unknown and the pace of recovery may vary from market to market, resulting in a high degree of uncertainty for potentially extended periods of time.

● New Fund Risk. The Funds are newly organized, diversified management investment companies with no operating history. As a result, prospective investors have a limited track record on which to base their investment decision. 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 any or all of the Funds. Like other new funds, large inflows and outflows may impact any of the Funds’ market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected. If any of the Funds fails to attract a large amount of assets, shareholders of the Fund may incur higher expenses as the Fund’s fixed costs would be allocated over a smaller number of shareholders.

● Passive Investment Risk. The Funds are not actively managed and the Adviser will not sell shares of a security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from an Underlying Index or the selling of shares of that security is otherwise required upon a reconstitution of an Underlying Index as addressed in the Index methodology. The Funds invest in securities included in, or representative of securities included in, the Underlying Indices, regardless of their investment merits. The Funds do not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Funds.

● Reinvestment Risk. Reinvestment risk is the risk that income from the Funds’ portfolios will decline if and when the Fund reinvests the proceeds from the disposition of portfolio securities at market interest rates that are below the portfolio's current earnings rate. A decline in income could negatively affect the market price of a Fund’s Shares.

● Tracking Error Risk. The Funds may be subject to tracking error, which is the divergence of a Fund’s performance from that of its Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in a Fund’s portfolio and those included in the corresponding Underlying Index, pricing differences, transaction costs incurred by the a Fund, a Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the an Underlying Index or the costs to a Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because a Fund incurs fees and expenses, while its Underlying Index does not.

65 

● 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 risk. U.S. Government obligations are subject to low but varying degrees of credit risk and are still subject to interest rate and market risk. From time to time, uncertainty regarding congressional action to increase the statutory debt ceiling could: i) increase the risk that the U.S. Government may default on payments on certain U.S. Government securities; ii) cause the credit rating of the U.S. Government to be downgraded or increase volatility in both stock and bond markets; iii) result in higher interest rates; iv) reduce prices of U.S. Treasury securities; and/or v) increase the costs of certain kinds of debt. U.S. Government obligations may be adversely affected by a default by, or decline in the credit quality of, the U.S. Government. In the past, U.S. sovereign credit has experienced downgrades, and there can be no guarantee that it will not be downgraded in the future. Further, if a U.S. Government-sponsored entity is negatively impacted by legislative or regulatory action, is unable to meet its obligations, or its creditworthiness declines, the performance of the Fund will be adversely impacted.

Additional Information About Non-Principal Risks of the Funds. This section provides additional information regarding certain non-principal risks of investing in the Fund. The risks listed below could have a negative impact on any of the Funds’ performance and trading prices.

● Costs of Buying or Selling Shares Risk. Investors buying or selling Shares of a Fund in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of the Funds’ Shares. In addition, secondary market investors will also incur the cost of the difference between the price at which an investor is willing to buy a Fund’s Shares (the “bid” price) and the price at which an investor is willing to sell a Fund’s Shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid/ask spread.” The bid/ask spread varies over time for a Fund’s Shares based on trading volume and market liquidity, and is generally lower if a Fund’s Shares have more trading volume and market liquidity and higher if a Fund’s Shares have little trading volume and market liquidity. Further, a relatively small investor base in a Fund, asset swings in a Fund and/or increased market volatility may cause increased bid/ask spreads. Due to the costs of buying or selling a Fund’s Shares, including bid/ask spreads, frequent trading of a Fund’s Shares may significantly reduce investment results and an investment in a Fund’s Shares may not be advisable for investors who anticipate regularly making small investments.

● Legal and Regulatory Change Risk.  The regulatory environment for investment companies is evolving, and changes in regulation may adversely affect the value of any of the Funds’ investments and each Fund’s ability to pursue its trading strategy.  In addition, the securities markets are subject to comprehensive statutes and regulations.  The SEC and other regulators and self-regulatory organizations and exchanges are authorized to take extraordinary actions in the event of market emergencies.  The effect of any future regulatory change on the Funds could be substantial and adverse.

● Regulated Investment Company (“RIC”) Compliance Risk.  Each of the Funds has elected to be, and intends to qualify each year for treatment as, a RIC under Subchapter M of Subtitle A, Chapter 1, of the Code.  To continue to qualify for federal income tax treatment as a RIC, a Fund must meet certain source-of-income, asset diversification and annual distribution requirements.  If for any taxable year a Fund fails to qualify for the special federal income tax treatment afforded to RICs, all of that Fund’s taxable income will be subject to federal income tax at regular corporate rates (without any deduction for distributions to its shareholders) and its income available for distribution will be reduced.  Under certain circumstances, a Fund could cure a failure to qualify as a RIC, but in order to do so, that Fund could incur significant Fund-level taxes and could be forced to dispose of certain assets.

Disclosure of Portfolio Holdings

The Funds’ entire portfolio holdings are publicly disseminated each day the Funds are open for business through the Funds’ website located at www.ustreasuryetf.com and may be made available through financial reporting and news services or any other medium, including publicly available internet web sites. Additional information regarding the Funds’ policies and procedures with respect to the disclosure of the Funds’ portfolio securities is available in the Funds’ Statement of Additional Information ("SAI").

MANAGEMENT OF THE FUNDS

The Board of Company, of which the Funds are each a series, is responsible for supervising the operations and affairs of the Funds. The Adviser is responsible for the daily management and administration of the Funds’ operations.

Investment Adviser

The investment adviser for each Fund is F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”). The Adviser is located at 3050 K Street NW, Suite W-201, Washington, DC 20007. The Adviser is controlled by F/m Acceleration, LLC, a Delaware limited liability company, and EQSF Holdings, LLC, a Delaware limited liability company owned by three officers of the Company. Subject to the overall supervision of the Board, the Adviser manages the overall investment operations of each Fund in accordance with the Fund’s investment objective and policies and formulates a continuing investment strategy for the Fund pursuant to the terms of investment advisory agreement between the Company and the Adviser (the “Advisory Agreement”). Under the terms of the Advisory Agreement, each Fund pays the Adviser a unitary management fee that is computed and paid monthly at an annual rate of 0.15% of each Fund’s average daily net assets during the month. From the unitary management fee, the Adviser pays most of the expenses of the Funds, including the cost of transfer agency, custody, fund administration, legal, audit and other services. However, under the Advisory Agreement, the Adviser is not responsible for interest expenses, brokerage commissions and other trading expenses, taxes and other extraordinary costs such as litigation and other expenses not incurred in the ordinary course of business. No information regarding the advisory fees paid by any of the Funds is currently available, as none of the Funds had commenced operations prior to the date of this Prospectus.

A discussion regarding the Board’s approval of the Funds’ Advisory Agreement and the factors the Board considered with respect to its approval will be available in the Funds’ next annual or semi-annual report to shareholders.

The Adviser’s Investment Management Team

Peter Baden and Alexander Morris serve as each Fund’s portfolio managers and are jointly responsible for the portfolio management decisions for the Funds.

The SAI provides additional information about the compensation of each Portfolio Manager, other accounts managed by them, and their ownership of Shares of the Funds.

HOW TO BUY AND SELL SHARES

Each of the Funds issue and redeem its Shares at NAV only in Creation Units. Only APs may acquire Shares directly from each Fund, and only APs may tender their Shares for redemption directly to each Fund, at NAV. APs must be (i) a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the National Securities Clearing Corporation, a clearing agency that is registered with the SEC; or (ii) a DTC participant (as discussed below). In addition, each AP must execute a Participant Agreement that has been agreed to by the Distributor, and that has been accepted by the Transfer Agent, with respect to purchases and redemptions of Creation Units. Once created, Shares trade in the secondary market in quantities less than a Creation Unit.

Investors can only buy and sell Shares in secondary market transactions through brokers. Shares are listed for trading on the secondary market on Nasdaq Stock Market, LLC (the “Exchange”) and can be bought and sold throughout the trading day like other publicly traded securities.

When buying or selling a Fund’s Shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offer price in the secondary market on each leg of a round trip (purchase and sale) transaction. In addition, because secondary market transactions occur at market prices, you may pay more than NAV when you buy Shares and receive less than NAV when you sell those Shares.

Book Entry

Shares are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding Shares.

Investors owning a Fund’s Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all Funds’ Shares. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of a Fund’s Shares, you are not entitled to receive physical delivery of stock certificates or to have a Fund’s Shares registered in your name, and you are not considered a registered owner of a Fund’s Shares. Therefore, to exercise any right as an owner of a Fund’s Shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book entry or “street name” through your brokerage account.

68 

Share Trading Prices on the Exchange

Trading prices of the Funds’ Shares on the Exchange may differ from the Fund’s daily NAV. Market forces of supply and demand, economic conditions and other factors may affect the trading prices of Shares. To provide additional information regarding the indicative value of each Fund’s Shares, the Exchange or a market data vendor disseminates information every 15 seconds through the facilities of the Consolidated Tape Association, or other widely disseminated means, an updated “intraday indicative value” (“IIV”) for each Fund’s Shares as calculated by an information provider or market data vendor. The Funds are neither involved in nor responsible for any aspect of the calculation or dissemination of the IIVs and make no representation or warranty as to the accuracy of the IIVs. If the calculation of the IIV is based on the basket of Deposit Securities, such IIV may not represent the best possible valuation of the Funds’ portfolios because the basket of Deposit Securities does not necessarily reflect the precise composition of the current portfolio of any Fund at a particular point in time. The IIV should not be viewed as a “real-time” update of each Fund’s NAV because the IIV may not be calculated in the same manner as the NAV, which is computed only once a day, typically at the end of the business day. The IIV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the Deposit Securities.

Frequent Purchases and Redemptions of Shares

The Funds impose no restrictions on the frequency of purchases and redemptions of the Funds’ Shares. In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by any of the Funds’ shareholders. Purchases and redemptions by APs, who are the only parties that may purchase or redeem any Fund’s Shares directly with a Fund, are an essential part of the ETF process and help keep share trading prices in line with NAV. As such, the Funds accommodate frequent purchases and redemptions by APs. However, the Board has also determined that frequent purchases and redemptions for cash may increase tracking error and portfolio transaction costs and may lead to the realization of capital gains or loses. To minimize these potential consequences of frequent purchases and redemptions, the Funds employ fair value pricing and impose transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by any of the Funds in effecting trades. In addition, the Funds reserve the right to reject any purchase order at any time.

Determination of Net Asset Value

Each Fund’s NAV is calculated as of the scheduled close of regular trading on the NYSE, generally 4:00 p.m. Eastern Time, each day the NYSE is open for business. The NAV for each Fund is calculated by dividing that Fund’s net assets by its Shares outstanding.

In calculating its NAV, each Fund generally values its assets on the basis of market quotations, last sale prices, or estimates of value furnished by a pricing service or brokers who make markets in such instruments. If such information is not available for a security held by a Fund or is determined to be unreliable, the security will be valued at fair value estimates under guidelines established by the Board.

Fair Value Pricing

If market quotations are unavailable or deemed unreliable by the Funds’ administrator, in consultation with the Adviser, securities will be fair valued by the Adviser in accordance with procedures adopted by the Board and under the Board’s ultimate supervision. Relying on prices supplied by pricing services or dealers or using fair valuation involves the risk that the values used by a Fund to price its investments may be higher or lower than the values used by other investment companies and investors to price the same investments.

69 

DIVIDENDS, DISTRIBUTIONS, AND TAXES

Dividends and Distributions

Each Fund will distribute substantially all of its net investment income and net realized capital gains, if any, to its shareholders. Each Fund expects to declare and pay distributions, if any, monthly, however it may declare and pay distributions more or less frequently. Net realized capital gains (including net short-term capital gains), if any, will be distributed by each Fund at least annually.

Dividend Reinvestment Service

Brokers may make the DTC book-entry dividend reinvestment service available to their customers who own a Fund’s Shares.  If this service is available and used, dividend distributions of both income and capital gains will automatically be reinvested in additional whole Shares of that Fund purchased on the secondary market.  Without this service, investors would receive their distributions in cash. In order to achieve the maximum total return on their investments, investors are encouraged to use the dividend reinvestment service.  To determine whether the dividend reinvestment service is available and whether there is a commission or other charge for using this service, consult your broker.  Brokers may require a Fund’s shareholders to adhere to specific procedures and timetables.

Taxes

As with any investment, you should consider how your investment in shares of a Fund will be taxed. The tax information in this Prospectus is provided as general information. Except where otherwise indicated, the discussion relates to investors who are individual United States citizens or residents. You should consult your own tax professional about the tax consequences of an investment in a Fund’s Shares.

Unless your investment in a Fund’s Shares is made through a tax-exempt entity or tax-advantaged account, such as an IRA plan, you need to be aware of the possible tax consequences when: (i) a Fund makes distributions; (ii) you sell your Shares listed on the Exchange; and (iii) you purchase or redeem Creation Units.

Taxes on Distributions

For federal income tax purposes, distributions of investment income are generally taxable as ordinary income or qualified dividend income. Taxes on distributions of capital gains (if any) are determined by how long a Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares of a Fund. Sales of assets held by a Fund for more than one year generally result in long-term capital gains and losses, and sales of assets held by a Fund for one year or less generally result in short-term capital gains and losses. Distributions of a Fund’s net capital gain (the excess of net long-term capital gains over net short-term capital losses) that are reported by that Fund as capital gain dividends (“Capital Gain Dividends”) will be taxable as long-term capital gains, which for non-corporate shareholders are subject to tax at reduced rates. Distributions of short-term capital gain will generally be taxable as ordinary income. Dividends and distributions are generally taxable to you whether you receive them in cash or reinvest them in additional Shares of a Fund.

Shortly after the close of each calendar year, you will be informed of the character of any distributions received from the Funds.

U.S. individuals with income exceeding specified thresholds are subject to a 3.8% Medicare contribution tax on all or a portion of their “net investment income,” which includes interest, dividends, and certain capital gains (including capital gains distributions and capital gains realized on the sale of shares of the Fund). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts.

In general, your distributions are subject to federal income tax for the year in which they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year. Distributions are generally taxable even if they are paid from income or gains earned by a Fund before your investment (and thus were included in the shares’ NAV when you purchased your shares of a Fund). Income from U.S. treasury securities are generally exempt from state and local taxes. Tax-exempt interest income is not included in net investment income for purposes of the federal net investment tax. Distributions paid from any interest income that is not tax-exempt and from any short-term or long-term capital gains will be taxable whether you reinvest those distributions or receive them in cash. Distributions paid from a Fund’s net long-term capital gains, if any, are taxable to you as long-term capital gains, regardless of how long you have held your shares.

70 

You may wish to avoid investing in a Fund shortly before a dividend or other distribution, because such a distribution will generally be taxable to you even though it may economically represent a return of a portion of your investment. This adverse tax result is known as “buying into a dividend.”

Taxes When Shares are Sold on the Exchange

For federal income tax purposes, any capital gain or loss realized upon a sale of shares of a Fund generally is treated as a long-term capital gain or loss if those shares have been held for more than 12 months and as a short-term capital gain or loss if those shares have been held for 12 months or less. However, any capital loss on a sale of shares held for six months or less is treated as long-term capital loss to the extent of Capital Gain Dividends paid with respect to such shares of a Fund. Any loss realized on a sale will be disallowed to the extent shares of a Fund are acquired, including through reinvestment of dividends, within a 61-day period beginning 30 days before and ending 30 days after the sale of shares. If disallowed, the loss will be reflected in an upward adjustment to the basis of the shares acquired.

IRAs and Other Tax-Qualified Plans

The one major exception to the preceding tax principles is that distributions on and sales of shares of a Fund held in an IRA (or other tax-qualified plan) will not be currently taxable unless it borrowed to acquire the shares.

U.S. Tax Treatment of Foreign Shareholders

If you are neither a resident nor a citizen of the United States or if you are a foreign entity, distributions (other than Capital Gain Dividends) paid to you by a Fund will generally be subject to a U.S. withholding tax at the rate of 30%, unless a lower treaty rate applies. The Funds may, under certain circumstances, report all or a portion of a dividend as an “interest-related dividend” or a “short-term capital gain dividend,” which would generally be exempt from this 30% U.S. withholding tax, provided certain other requirements are met.

Foreign shareholders will generally not be subject to U.S. tax on gains realized on the sale of Funds’ Shares, except that a nonresident alien individual who is present in the United States for 183 days or more in a calendar year will be taxable on such gains and on capital gain dividends from the Fund.

In contrast, if a foreign investor conducts a trade or business in the United States and the investment in a Fund is effectively connected with that trade or business, then the foreign investor’s income from that Fund will generally be subject to U.S. federal income tax at graduated rates in a manner similar to the income of a U.S. citizen or resident.

The Funds are generally required to withhold 30% on certain payments to shareholders that are foreign entities and that fail to meet prescribed information reporting or certification requirements.

All foreign investors should consult their own tax advisors regarding the tax consequences in their country of residence of an investment in any of the Funds.

Backup Withholding

Each Fund (or a financial intermediary, such as a broker, through which a shareholder owns shares of a Fund) generally is required to withhold and remit to the U.S. Treasury a percentage of the taxable distributions and sale or redemption proceeds paid to any shareholder who fails to properly furnish a correct taxpayer identification number, who has underreported dividend or interest income, or who fails to certify that he, she or it is not subject to such backup withholding. The current backup withholding rate is 24%.

71 

Taxes on Purchases and Redemptions of Creation Units

An AP having the U.S. dollar as its functional currency for U.S. federal income tax purposes who exchanges securities for Creation Units generally recognizes a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time of the exchange and the sum of the AP’s aggregate basis in the securities surrendered plus the amount of cash paid for such Creation Units. The Internal Revenue Service (“IRS”), however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Any gain or loss realized by an AP upon a creation of Creation Units will be treated as capital gain or loss if the AP holds the securities exchanged therefor as capital assets, and otherwise will be ordinary income or loss. Any capital gain or loss realized upon the creation of Creation Units will generally be treated as long-term capital gain or loss if the securities exchanged for such Creation Units have been held by the AP for more than 12 months, and otherwise will be short-term capital gain or loss.

The Company on behalf of the Funds has the right to reject an order for a purchase of Creation Units if the AP (or a group of APs) would, upon obtaining the Creation Units so ordered, own 80% or more of the outstanding shares of any of the Funds and if, pursuant to Section 351 of the Code, any of the Funds would have a basis in the securities different from the market value of such securities on the date of deposit. The Company also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination. If a Fund does issue Creation Units to an AP (or group of APs) that would, upon obtaining the Creation Units so ordered, own 80% or more of the outstanding shares of a Fund, the AP (or group of APs) may not recognize gain or loss upon the exchange of securities for Creation Units.

An AP who redeems Creation Units will generally recognize a gain or loss equal to the difference between the sum of the aggregate market value of any securities received plus the amount of any cash received for such Creation Units and the AP’s basis in the Creation Units. Any gain or loss realized by an AP upon a redemption of Creation Units will be treated as capital gain or loss if the AP holds the shares comprising the Creation Units as capital assets, and otherwise will be ordinary income or loss. Any capital gain or loss realized upon the redemption of Creation Units will generally be treated as long-term capital gain or loss if the shares comprising the Creation Units have been held by the AP for more than 12 months, and otherwise will generally be short-term capital gain or loss. Any capital loss realized upon a redemption of Creation Units held for six months or less will be treated as a long-term capital loss to the extent of any amounts treated as distributions to the applicable AP of long-term capital gains with respect to the Creation Units (including any amounts credited to the AP as undistributed capital gains).

The Funds may include a payment of cash in addition to, or in place of, the delivery of a basket of securities upon the redemption of Creation Units. The Funds may sell portfolio securities to obtain the cash needed to distribute redemption proceeds. This may cause a Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, a Fund may be less tax efficient if it includes such a cash payment in the proceeds paid upon the redemption of Creation Units.

Persons purchasing or redeeming Creation Units should consult their own tax advisers with respect to the tax treatment of any creation or redemption transaction.

The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in the Funds. It is not a substitute for personal tax advice. You also may be subject to state and local tax on a Fund’s distributions and sales of shares of a Fund. Consult your personal tax advisor about the potential tax consequences of an investment in Shares of the Funds under all applicable tax laws. For more information, please see the section entitled “DIVIDENDS, DISTRIBUTIONS, AND TAXES” in the SAI.

DISTRIBUTION

The Distributor, Quasar Distributors, LLC, is a broker-dealer registered with the SEC. The Distributor distributes Creation Units for the Fund on an agency basis and does not maintain a secondary market in Shares. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is 111 East Kilbourn Avenue, Suite 2200, Milwaukee, Wisconsin 53202.

ADDITIONAL CONSIDERATIONS

Payments to Financial Intermediaries

The Adviser and its affiliates, out of their own resources and without additional cost to the Funds or their shareholders, may pay intermediaries, including affiliates of the Adviser, for the sale of Funds’ Shares and related services, including participation in activities that are designed to make intermediaries more knowledgeable about exchange traded products.  Payments are generally made to intermediaries that provide shareholder servicing, marketing and related sales support, educational training or support, or access to sales meetings, sales representatives and management representatives of the intermediary.  Payments may also be made to intermediaries for making Shares of the Funds available to their customers generally and in investment programs.  The Adviser and its affiliates may also reimburse expenses or make payments from their own resources to intermediaries in consideration of services or other activities the Adviser believes may facilitate investment in the Fund.

The possibility of receiving, or the receipt of, the payments described above may provide intermediaries or their salespersons with an incentive to favor sales of Shares of any of the Funds, and other funds whose affiliates make similar compensation available, over other investments that do not make such payments.  Investors may wish to take such payment arrangements into account when considering and evaluating any recommendations relating to the Fund and other ETFs.

Premium/Discount Information

Information regarding how often each of the Fund’s Shares traded on the Exchange at a price above (i.e., at a premium) or below (i.e., at a discount) the NAV is available, free of charge, on the Fund’s website at www.ustreasuryetf.com.

Continuous Offering

The method by which Creation Units are purchased and traded may raise certain issues under applicable securities laws.  Because new Creation Units are issued and sold by the Fund on an ongoing basis, at any point a “distribution,” as such term is used in the Securities Act of 1933, as amended (the “Securities Act”), may occur.  Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the Prospectus delivery and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into individual Shares, and sells such Shares directly to customers, or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares.  A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in Shares, whether or not participating in the distribution of Shares, are generally required to deliver a prospectus.  This is because the prospectus delivery exemption in Section 4(a)(3) of the Securities Act is not available with respect to such transactions as a result of Section 24(d) of the 1940 Act.  As a result, broker dealer-firms should note that dealers who are not underwriters but are participating in a distribution (as contrasted with ordinary secondary market transactions) and thus dealing with Funds’ Shares that are part of an over-allotment within the meaning of Section 4(a)(3)(a) of the Securities Act would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act.  Firms that incur a prospectus delivery obligation with respect to Shares of the Funds are reminded that under Rule 153 of the Securities Act, a prospectus delivery obligation under Section 5(b)(2) of the Securities Act owed to an exchange member in connection with a sale on the Exchange is satisfied by the fact that the Funds’ Prospectus is available on the SEC’s electronic filing system.  The prospectus delivery mechanism provided in Rule 153 of the Securities Act is only available with respect to transactions on an exchange.

73 

Additional Information

The Funds enter into contractual arrangements with various parties, including among others the Funds’ investment adviser, who provides services to the Funds.  Shareholders are not parties to, or intended (or “third party”) beneficiaries of, those contractual arrangements.

The Prospectus and the SAI provide information concerning the Funds that you should consider in determining whether to purchase Shares of any of the Funds.  The Funds may make changes to this information from time to time.  Neither this Prospectus nor the SAI is intended to give rise to any contract rights or other rights in any shareholder, other than any rights conferred explicitly by federal or state securities laws that may not be waived.

NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY REPRESENTATIONS NOT CONTAINED IN THIS PROSPECTUS OR IN THE FUND’S SAI INCORPORATED HEREIN BY REFERENCE, IN CONNECTION WITH THE OFFERING MADE BY THIS PROSPECTUS AND, IF GIVEN OR MADE, SUCH REPRESENTATIONS MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED BY THE COMPANY OR ITS DISTRIBUTOR. THIS PROSPECTUS DOES NOT CONSTITUTE AN OFFERING BY THE COMPANY OR BY THE DISTRIBUTOR IN ANY JURISDICTION IN WHICH SUCH OFFERING MAY NOT LAWFULLY BE MADE.

FUND HISTORY

The Company is an open-end management investment company currently consisting of 50 separate portfolios.  The Company is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), and was organized as a Maryland corporation on February 29, 1988.  This SAI pertains to shares of the US Treasury 30 Year Bond ETF, US Treasury 20 Year Bond ETF, US Treasury 10 Year Note ETF, US Treasury 7 Year Note ETF, US Treasury 5 Year Note ETF, US Treasury 3 Year Note ETF, US Treasury 2 Year Note ETF, US Treasury 12 Month Bill ETF, US Treasury 6 Month Bill ETF, US Treasury 3 Month Bill ETF. F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) serves as the investment adviser to each Fund.

The investment objective of each Fund is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of its corresponding benchmark index (“Underlying Index”):

Fund	Underlying Index
UST 30 Year	ICE BofA Current 30-Year US Treasury Index (GA30)
UST 20 Year	ICE BofA Current 20-Year US Treasury Index (GA20)
UST 10 Year	ICE BofA Current 10-Year US Treasury Index (GA10)
UST 7 Year	ICE BofA Current 7-Year US Treasury Index (GA07)
UST 5 Year	ICE BofA Current 5-Year US Treasury Index (GA05)
UST 3 Year	ICE BofA Current 3-Year US Treasury Index (GA03)
UST 2 Year	ICE BofA Current 2-Year US Treasury Index (GA02)
UST 12 Month	ICE BofA US 1-Year Treasury Bill Index (G0O3)
UST 6 Month	ICE BofA US 6-Month Treasury Bill Index (G0O2)
UST 3 Month	ICE BofA US 3-Month Treasury Bill Index (G0O1)

Each Fund offers and issues shares at its net asset value per share (“NAV”) only in aggregations of a specified number of shares (each a “Creation Unit”).  Each Fund also generally offers and issues shares in exchange for a basket of securities (“Deposit Securities”) together with the deposit of a specified cash payment (“Cash Component”).  The Company reserves the right to permit or require the substitution of a “cash in lieu” amount (“Deposit Cash”) to be added to the Cash Component to replace any Deposit Security. The shares of the Funds are listed on the Nasdaq (the “Exchange”) and trade on the Exchange at market prices. These prices may differ from a Fund’s NAV.  The shares are also redeemable only in Creation Unit aggregations, and generally in exchange for portfolio securities and a specified cash payment.  Creation Units generally consist of 10,000 shares, though this may change from time to time.

Shares of a Fund may be issued in advance of receipt of Deposit Securities subject to various conditions including a requirement to maintain on deposit with the Company cash at least equal to a specified percentage of the market value of the missing Deposit Securities as set forth in the Participant Agreement (as defined below).  The Company may impose a transaction fee for each creation or redemption (the “Transaction Fee”).  In all cases, such fees will be limited in accordance with the requirements of the Securities and Exchange Commission (the "SEC") applicable to management investment companies offering redeemable securities.  The Funds may charge, either in lieu or in addition to the fixed creation or redemption Transaction Fee, a variable fee for creations and redemptions in order to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from such transaction, up to a maximum of 2.00% of the NAV per Creation Unit, inclusive of any Transaction Fees charged (if applicable).

INVESTMENT POLICIES AND PRACTICES

The Funds’ investment objectives and principal investment strategies are described in the Prospectus. The sections below describe some of the different types of investments that may be made by the Funds as part of its non-principal investment strategy. The following information supplements, and should be read in conjunction with, the Prospectus.

With respect to the Funds’ investments, unless otherwise noted, if a percentage limitation on investment is adhered to at the time of investment or contract, a subsequent increase or decrease as a result of market movement or redemption will not result in a violation of such investment limitation.

1

During unusual economic or market conditions, or for temporary defensive or liquidity purposes, any of the Funds may invest up to 100% of its assets in money market instruments that would not ordinarily be consistent with that Fund’s objective.

There can be no guarantee that the Funds will achieve their investment objectives.  The Funds may not necessarily invest in all of the instruments or use all of the investment techniques permitted by the Funds’ Prospectus and this SAI, or invest in such instruments or engage in such techniques to the full extent permitted by the Funds’ investment policies and limitations

Cash Equivalents and Short-Term Investments

The Funds may invest in cash, cash equivalents, and a variety of short-term instruments in such proportions as warranted by prevailing market conditions and the Funds’ principal investment strategies. The Funds may temporarily invest without limit in such instruments for liquidity purposes, or in an attempt to respond to adverse market, economic, political or other conditions. During such periods, a Fund may not be able to achieve its investment objective.

Short-term instruments include obligations of the U.S. government or its agencies or instrumentalities (see “U.S. Government Securities” below) and, without limitation, the following:

(1)          Certificates of Deposit. The Funds may invest in certificates of deposit issued against funds deposited in a bank or savings and loan association. Such certificates are for a definite period of time, earn a specified rate of return, and are normally negotiable. If such certificates of deposit are non-negotiable, they will be considered illiquid investments and be subject to the Fund’s 15% restriction on investments in illiquid investments. Pursuant to the certificate of deposit, the issuer agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Under current FDIC regulations, the maximum insurance payable as to any one certificate of deposit is $250,000; therefore, certificates of deposit purchased by the Fund may not be fully insured.

(2)          Bankers’ Acceptances. The Funds may invest in bankers’ acceptances, which are short-term credit instruments used to finance commercial transactions. Generally, an acceptance is a time draft drawn on a bank by an exporter or an importer to obtain a stated amount of funds to pay for specific merchandise. The draft is then “accepted” by a bank that, in effect, unconditionally guarantees to pay the face value of the instrument on its maturity date. The acceptance may then be held by the accepting bank as an asset or it may be sold in the secondary market at the going rate of interest for a specific maturity.

(3)          Repurchase Agreements. The Funds may invest in repurchase agreements which involve purchases of debt securities. In such an action, at the time the Fund purchases the security, it simultaneously agrees to resell and redeliver the security to the seller, who also simultaneously agrees to buy back the security at a fixed price and time. This assures a predetermined yield for the Fund during its holding period since the resale price is always greater than the purchase price and reflects an agreed-upon market rate. Such actions afford an opportunity for the Funds to invest temporarily available cash. The Funds may enter into repurchase agreements only with respect to certain obligations. For the Funds, collateral may consist of any fixed income security which is an eligible investment for the Funds entering into the repurchase agreement. The Funds’ custodian will hold the securities underlying any repurchase agreement, or the securities will be part of the Federal Reserve/Treasury Book Entry System. The market value of the collateral underlying the repurchase agreement will be determined on each business day. If at any time the market value of the collateral falls below the repurchase price under the repurchase agreement (including any accrued interest), the Funds will promptly receive additional collateral (so the total collateral is an amount at least equal to the repurchase price plus accrued interest). Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Funds is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in the event of default, the repurchase agreement provides that the Funds are entitled to sell the underlying collateral. If the value of the collateral declines after the agreement is entered into, however, and if the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase price, the Funds could incur a loss of both principal and interest. The portfolio managers monitor the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. The portfolio managers do so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Funds. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Funds to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

(4)          Bank Time Deposits. The Funds may invest in bank time deposits, which are monies kept on deposit with banks or savings and loan associations for a stated period of time at a fixed rate of interest. There may be penalties for the early withdrawal of such time deposits, in which case the yields of these investments will be reduced.

(5)          Eurodollar and Yankee Instruments. The Funds may invest in Eurodollar certificates of deposit issued by foreign branches of U.S. or foreign banks; Eurodollar time deposits, which are U.S. dollar-denominated deposits in foreign branches of U.S. or foreign banks; and Yankee certificates of deposit, which are U.S. dollar-denominated certificates of deposit issued by U.S. branches of foreign banks and held in the United States. In each instance, the Fund may only invest in bank instruments issued by an institution which has capital, surplus and undivided profits of more than $100 million or the deposits of which are insured by the Bank Insurance Fund or the Savings Association Insurance Fund.

2

(6)          Money Market Funds and Short-Term Debt Funds. The Funds may invest in money market funds. The Funds will each bear their proportionate share of the money market fund’s fees and expenses (see “Other Investment Companies” below). The Funds may hold securities of other mutual funds that invest primarily in debt obligations with remaining maturities of 13 months or less.

Illiquid Investments 

Pursuant to Rule 22e-4 under the 1940 Act, a Fund may invest up to 15% of its net assets in illiquid investments. An illiquid investment as defined in Rule 22e-4 is an investment that a Fund reasonably expects cannot be sold or disposed of in current market conditions within 7 calendar days or less without the sale or disposition significantly changing the market value of the investment. These investments may include restricted securities and repurchase agreements maturing in more than 7 days. Restricted securities are securities that may not be sold to the public without an effective registration statement under the Securities Act of 1933, as amended (the “1933 Act”), and thus may be sold only in privately negotiated transactions or pursuant to an exemption from registration. Subject to the adoption of guidelines by the Board of Directors of the Company (“Board”), certain restricted securities that may be sold to institutional investors pursuant to Rule 144A under the 1933 Act and non-exempt commercial paper may be determined to be liquid by the Adviser. Illiquid investments involve the risk that the investments will not be able to be sold at the time the Adviser desires or at prices approximating the value at which a Fund is carrying the investments. To the extent an investment held by a Fund is deemed to be an illiquid investment or a less liquid investment, a Fund will be exposed to a greater liquidity risk.

The Company has implemented a liquidity risk management program and related procedures to identify illiquid investments pursuant to Rule 22e-4. If the limitation on illiquid investments is exceeded, other than by a change in market values, the condition will be reported to the Board and, when required by the Liquidity Rule, to the SEC.

Inflation Protected Securities 

Each Fund may invest in inflation protected securities. Inflation protected securities are fixed income securities designed to provide protection against the negative effects of inflation. Two structures are common. The U.S. Treasury and some other issuers use a structure that accrues inflation into the principal value of the bond. Most other issuers pay out the inflation accruals as part of a semiannual coupon.

Inflation protected securities issued by the U.S. Treasury have maturities of five, ten, twenty or thirty years, although it is possible that securities with other maturities will be issued in the future. The U.S. Treasury securities pay interest on a semi-annual basis, equal to a fixed percentage of the inflation-adjusted principal amount. For example, if a Fund purchased an inflation protected bond with a par value of $1,000 and a 3% real rate of return coupon (payable 1.5% semi-annually), and inflation over the first six months was 1%, the mid-year par value of the bond would be $1,010 and the first semi-annual interest payment would be $15.15 ($1,010 times 1.5%). If inflation during the second half of the year resulted in the whole years’ inflation equaling 3%, the end-of-year par value of the bond would be $1,030 and the second semi-annual interest payment would be $15.45 ($1,030 times 1.5%).

If the periodic adjustment rate measuring inflation falls, the principal value of U.S. Treasury inflation protected securities will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation protected bonds, even during a period of deflation. However, the current market value of the bonds is not guaranteed, and will fluctuate. Other inflation-protected securities that accrue inflation into their principal value may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

The value of inflation-protected securities is expected to change in response to changes in real interest rates. Real interest rates in turn are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation protected securities. In contrast, if nominal interest rates increased at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-protected securities.

The periodic adjustment of U.S. inflation protected bonds is tied to the Consumer Price Index for Urban Consumers (“CPI-U”), which is calculated monthly by the U.S. Bureau of Labor Statistics. The CPI-U is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy. Inflation protected securities issued by a foreign government are generally adjusted to reflect a comparable inflation index, calculated by that government. There can be no assurance that the CPI-U or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will be correlated to the rate of inflation in the United States. If the market perceives that the adjustment mechanism of an inflation-protected security does not accurately adjust for inflation, the value of the security could be adversely affected.

3

While inflation protected securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. The calculation of the inflation index ratio for inflation protected securities issued by the U.S. Treasury incorporates an approximate three-month lag, which may have an effect on the trading price of the securities, particularly during periods of significant, rapid changes in the inflation index. To the extent that inflation has increased during the three months prior to an interest payment, that interest payment will not be protected from the inflation increase. Further, to the extent that inflation has increased during the final three months of a security’s maturity, the final value of the security will not be protected against that increase, which will negatively impact the value of the security. If interest rates rise due to reasons other than inflation (for example, due to changes in currency exchange rates), investors in inflation-protected securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

Any increase in the principal amount of an inflation-protected security will be considered taxable income to the Fund, even though the Fund does not receive its principal until maturity.

Lending Portfolio Securities 

A Fund may lend its portfolio securities to brokers, dealers, and financial institutions in an amount not exceeding 33 1/3% of the value of a Fund’s total assets. These loans will be secured by collateral (consisting of cash, U.S. Government Securities, or irrevocable letters of credit) maintained in an amount equal to at least 100% of the market value, determined daily, of the loaned securities. A Fund may, subject to certain notice requirements, at any time call the loan and obtain the return of the securities loaned. A Fund will be entitled to payments equal to the interest and dividends on the loaned securities and may receive a premium for lending the securities. The advantage of such loans is that a Fund continues to receive the income on the loaned securities while earning interest on the cash amounts deposited as collateral, which will be invested in short-term investments.

A loan may be terminated by the borrower on one business day’s notice, or by the Company on two business days’ notice. If the borrower fails to deliver the loaned securities within four days after receipt of notice, the Company may use the collateral to replace the securities while holding the borrower liable for any excess of replacement cost exceeding the collateral. As with any extensions of credit, there are risks of delay in recovery and, in some cases, even loss of rights in the collateral, should the borrower of the securities fail financially. In addition, securities lending involves a form of leverage, and a Fund may incur a loss if securities purchased with the collateral from securities loans decline in value or if the income earned does not cover a Fund’s transaction costs. However, loans of securities will be made only to companies the Board deems to be creditworthy (such creditworthiness will be monitored on an ongoing basis) and when the income that can be earned from such loans justifies the attendant risks. Upon termination of the loan, the borrower is required to return the securities. Any gain or loss in the market price during the loan period would inure to the Fund.

When voting or consent rights that accompany loaned securities pass to the borrower, the Company will follow the policy of calling the loaned securities, to be delivered within one day after notice, to permit the exercise of such rights if the matters involved would have a material effect on the investment in such loaned securities. A Fund will pay reasonable finder’s, administrative, and custodial fees in connection with loans of securities.

LIBOR Discontinuance or Unavailability Risk 

Many financial instruments may be tied to the London Interbank Offered Rate, or “LIBOR,” to determine payment obligations, financing terms, hedging strategies, or investment value. LIBOR is the offered rate for short-term Eurodollar deposits between major international banks. As of December 31.2021, all non-U.S. dollar LIBOR publications have been phased out and a majority of U.S. dollar LIBOR settings will cease publication after June 30, 2023. It is possible that a subset of LIBOR settings will be published after these dates on a “synthetic” basis, but any such publications would be considered non-representative of the underlying market. The U.S. Federal Reserve, based on the recommendations of the New York Federal Reserve's Alternative Reference Rate Committee (comprised of major derivative market participants and their regulators), has begun publishing SOFR that is intended to replace U.S. dollar LIBOR. Proposals for alternative reference rates for other currencies have also been announced or have already begun publication. Markets are slowly developing in response to these new reference rates. Uncertainty related to the liquidity impact of the change in rates, and how to appropriately adjust these rates at the time of transition, poses risks for the Fund. The effect of any changes to, or discontinuation of, LIBOR on the Fund will depend on, among other things, (1) existing fallback or termination provisions in individual contracts and (2) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new instruments and contracts. The expected discontinuation of LIBOR could have a significant impact on the financial markets in general and may also present heightened risk to market participants, including public companies, investment advisers, investment companies, and broker-dealers. The risks associated with this discontinuation and transition will be exacerbated if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely manner. For example, current information technology systems may be unable to accommodate new instruments and rates with features that differ from LIBOR. Accordingly, it is difficult to predict the full impact of the transition away from LIBOR on the Fund until new reference rates and fallbacks for both legacy and new instruments and contracts are commercially accepted and market practices become settled.

Other Investment Companies 

Each Fund may invest in other investment companies, including open-end funds, closed-end funds, unit investment trusts, and exchange-traded funds (“ETFs”) registered under the 1940 Act that invest primarily in Fund eligible investments. Under the 1940 Act, a Fund’s investment in such securities is generally limited to 3% of the total voting stock of any one investment company; 5% of such Fund’s total assets with respect to any one investment company; and 10% of such Fund’s total assets in the aggregate. A Fund’s investments in other investment companies may include money market mutual funds. Investments in money market funds are not subject to the percentage limitations set forth above.

Many ETFs, however, have obtained exemptive relief from the SEC to permit unaffiliated funds to invest in their shares beyond these statutory limits, subject to certain conditions and pursuant to contractual arrangements between the ETFs and the investing funds. A Fund may rely on these exemptive orders that permit a Fund to invest in these ETFs beyond the limits contained in the 1940 Act, subject to certain terms and conditions. Generally, these terms and conditions require the Board to approve policies and procedures relating to certain of a Fund’s investments in ETFs. These policies and procedures require, among other things, that (i) the Adviser conducts a Fund’s investment in ETFs without regard to any consideration received by the Fund or any of its affiliated persons and (ii) the Adviser certifies to the Board quarterly that it has not received any consideration in connection with an investment by a Fund in an ETF, or if it has, the amount and purpose of the consideration will be reported to the Board and an equivalent amount of advisory fees shall be waived by the Adviser.

The SEC recently adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in the securities of another investment company. These changes include, among other things, the rescission of certain SEC exemptive orders permitting investments in excess of the statutory limits and the withdrawal of certain related SEC staff no-action letters, and the adoption of Rule 12d1-4 under the 1940 Act. Rule 12d1-4 permits a Fund to invest in other investment companies beyond the statutory limits, subject to certain conditions. Notable conditions include those relating to: (i) control and voting that prohibit an acquiring fund, its investment adviser and their respective affiliates from beneficially owning more than 25% of the outstanding voting securities of an unaffiliated acquired fund; (ii) certain required findings relating to complexity, fees and undue influence (among other things); (iii) fund of funds investment agreements; and (iv) general limitations on an acquired fund’s investments in other investment companies and private funds to no more than 10% of the acquired fund’s asset, except in certain circumstances.

ETFs in which a Fund may invest are a type of index fund bought and sold on a securities exchange. An ETF trades like common stock and represents a portfolio of securities designed to track a particular market index. ETFs can give exposure to all or a portion of the U.S. market, a foreign market, a region, a commodity, a currency, or to any other index that an ETF tracks. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. An ETF may fail to accurately track the returns of the market segment or index that it is designed to track, and the price of an ETF’s shares may fluctuate. In addition, because they, unlike traditional mutual funds, are traded on an exchange, ETFs are subject to the following risks: (i) the performance of the ETF may not replicate the performance of the underlying index that it is designed to track; (ii) the market price of the ETF’s shares may trade at a premium or discount to the ETF’s NAV; (iii) an active trading market for an ETF may not develop or be maintained; and (iv) there is no assurance that the requirements of the exchange necessary to maintain the listing of the ETF will continue to be met or remain unchanged. Trading in an ETF may be halted if the trading in one or more of the ETF’s underlying securities is halted, which could result in the ETF being more volatile. In the event substantial market or other disruptions affecting ETFs should occur in the future, the liquidity and value of the Fund’s shares could also be substantially and adversely affected.

If a Fund invests in other investment companies, Fund shareholders will bear not only their proportionate share of the Fund’s expenses, but also, indirectly, the similar expenses of the underlying investment companies. Shareholders would also be exposed to the risks associated not only with the Fund, but also with the portfolio investments of the underlying investment companies. Shares of certain closed-end funds may at times be acquired at market prices representing premiums to their NAVs. Shares acquired at a premium to their NAV may be more likely to subsequently decline in price, resulting in a loss to the Fund and its shareholders.

U.S. Government Securities 

Each Fund may invest in U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest, which are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities. U.S. government agency securities include securities issued by (a) the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, and the Government National Mortgage Association, whose securities are supported by the full faith and credit of the United States; (b) the Federal Home Loan Banks, Federal Intermediate Credit Banks, and the Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury; (c) the Federal National Mortgage Association, whose securities are supported by the discretionary authority of the U.S. government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. government provides financial support to such U.S. government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law. The U.S. government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate.

U.S. Treasury obligations include separately traded interest and principal component parts of such obligations, known as Separately Traded Registered Interest and Principal Securities (“STRIPS”), which are transferable through the Federal book-entry system. STRIPS are sold as zero-coupon securities, which means that they are sold at a substantial discount and redeemed at face value at their maturity date without interim cash payments of interest or principal. This discount is accreted over the life of the security, and such accretion will constitute the income earned on the security for both accounting and tax purposes. Because of these features, such securities may be subject to greater interest rate volatility than interest paying U.S. Treasury obligations.

When-Issued and Delayed Delivery Transactions 

Each Fund may purchase securities on a when-issued or delayed delivery basis. When such a transaction is negotiated, the purchase price is fixed at the time the purchase commitment is entered, but delivery of and payment for the securities take place at a later date. A Fund will not accrue income with respect to securities purchased on a when-issued or delayed delivery basis prior to their stated delivery date.

The purchase of securities on a when-issued or delayed delivery basis exposes a Fund to risk because the securities may decrease in value prior to delivery. In addition, a Fund’s purchase of securities on a when-issued or delayed delivery basis while remaining substantially fully invested could increase the amount of a Fund’s total assets that are subject to market risk, resulting in increased sensitivity of NAV to changes in market prices. A seller’s failure to deliver securities to a Fund could prevent the Fund from realizing a price or yield considered to be advantageous.

When a Fund agrees to purchase securities on a when-issued or delayed delivery basis, a Fund will segregate cash or liquid securities in an amount sufficient to meet the Fund’s purchase commitments. It may be expected that a Fund’s net assets will fluctuate to a greater degree when it sets aside securities to cover such purchase commitments than when it sets aside cash. In addition, because a Fund will set aside cash or liquid securities to satisfy its purchase commitments, its liquidity and the ability of the Adviser to manage it might be affected in the event its commitments to purchase when-issued or delayed delivery securities ever became significant. Under normal market conditions, however, a Fund’s commitments to purchase when-issued or delayed delivery securities will not exceed 25% of the value of its total assets.

Zero-Coupon and Step Coupon Securities 

Each Fund may invest in zero-coupon and step coupon securities. Zero-coupon securities pay no cash income to their holders until they mature. When held to maturity, their entire return comes from the difference between their purchase price and their maturity value. Step coupon securities are debt securities that may not pay interest for a specified period of time and then, after the initial period, may pay interest at a series of different rates. Both zero-coupon and step coupon securities are issued at substantial discounts from their value at maturity. Because interest on these securities is not paid on a current basis, the values of securities of this type are subject to greater fluctuations than are the value of securities that distribute income regularly and may be more speculative than such securities. Accordingly, the values of these securities may be highly volatile as interest rates rise or fall. In addition, while such securities generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause a Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by the Code.

6

Temporary Investments 

During periods of adverse market or economic conditions, a Fund may temporarily invest all or a substantial portion of its assets in high-quality, fixed-income securities, money market instruments, and shares of money market mutual funds, or it may hold cash. At such times, a Fund would not be pursuing its stated investment objective with its usual investment strategies. A Fund may also hold these investments for liquidity purposes. Fixed-income securities will be deemed to be of high quality if they are rated “A” or better by S&P or Moody’s or, if unrated, are determined to be of comparable quality by the Adviser. Money market instruments are high-quality, short-term fixed-income obligations (which generally have remaining maturities of one year or less) and may include U.S. Government Securities, commercial paper, certificates of deposit and banker’s acceptances issued by domestic branches of U.S. banks that are members of the Federal Deposit Insurance Corporation, and repurchase agreements for U.S. Government Securities. In lieu of purchasing money market instruments, the Fund may purchase shares of money market mutual funds that invest primarily in U.S. Government Securities and repurchase agreements involving those securities, subject to certain limitations imposed by the 1940 Act. A Fund, as an investor in a money market fund, will indirectly bear that fund’s fees and expenses, which will be in addition to the fees and expenses of the Fund. Repurchase agreements involve certain risks not associated with direct investments in debt securities.

Portfolio Turnover 

Portfolio securities may be sold without regard to the time they have been held when investment considerations warrant such action. A higher portfolio turnover rate would result in higher brokerage costs to a Fund and could also result in the realization of larger amounts of capital gains, including short-term capital gains. Capital gains are generally taxable when distributed to shareholders, and distributions of short-term capital gains are generally taxable at ordinary income tax rates.

Pandemic Risk 

Disease outbreaks that affect local economies or the global economy may materially and adversely impact a Fund and/or the Adviser’s business. For example, uncertainties regarding the novel Coronavirus (“COVID-19”) outbreak have resulted in serious economic disruptions across the globe. These types of outbreaks can be expected to cause severe decreases in core business activities such as manufacturing, purchasing, tourism, business conferences and workplace participation, among others. These disruptions lead to instability in the market place, including stock market losses and overall volatility, as has occurred in connection with COVID-19. In the face of such instability, governments may take extreme and unpredictable measures to combat the spread of disease and mitigate the resulting market disruptions and losses. The Adviser has in place business continuity plans reasonably designed to ensure that it maintains normal business operations, and it periodically tests those plans. However, in the event of a pandemic or an outbreak, there can be no assurance that the Adviser or a Fund’s service providers will be able to maintain normal business operations for an extended period of time or will not lose the services of key personnel on a temporary or long-term basis due to illness or other reasons. Although vaccines for COVID-19 are becoming more widely available, the full impacts of a pandemic or disease outbreaks are unknown and the pace of recovery may vary from market to market, resulting in a high degree of uncertainty for potentially extended periods of time.

Cyber Security Risk 

A Fund and its service providers may be prone to operational and information security risks resulting from breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a Fund to lose proprietary information, suffer data corruption, or lose operational capacity. Breaches in cyber security include, among other behaviors, stealing or corrupting data maintained online or digitally, denial of service attacks on websites, the unauthorized release of confidential information or various other forms of cyber-attacks. Cyber security breaches affecting a Fund, the Adviser, custodian, transfer agent, intermediaries and other third-party service providers may adversely impact a Fund. For instance, cyber security breaches may interfere with the processing of shareholder transactions, impact a Fund’s ability to calculate its NAVs, cause the release of private shareholder information or confidential business information, impede trading, subject a Fund to regulatory fines or financial losses and/or cause reputational damage. A Fund may also incur additional costs for cyber security risk management purposes. Similar types of cyber security risks are also present for issuers of securities in which a Fund may invest, which could result in material adverse consequences for such issuers and may cause a Fund’s investment in such companies to lose value. While each Fund and its service providers have established IT and data security programs and have in place business continuity plans and other systems designed to prevent losses and mitigate cyber security risk, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified or that cyber-attacks may be highly sophisticated. Furthermore, a Fund has 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 a Fund and the Adviser.

INVESTMENT RESTRICTIONS

The Company has adopted the following investment restrictions as fundamental policies with respect to each Fund. These restrictions cannot be changed with respect to each Fund without the approval of the holders of a majority of that Fund’s outstanding voting securities. For the purposes of the 1940 Act, a “majority of outstanding shares” means the vote of the lesser of: (1) 67% or more of the voting securities of the Fund present at the meeting if the holders of more than 50% of the Fund’s outstanding voting securities are present or represented by proxy; or (2) more than 50% of the outstanding voting securities of the Fund.

7

Except with the approval of a majority of the outstanding voting securities, each Fund may not:

1. Concentrate its investments (i.e., hold more than 25% of its total assets) in any industry or group of related industries. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and tax-exempt securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.

2. Borrow money or issue senior securities (as defined under the 1940 Act), except to the extent permitted under the 1940 Act.

3. Make loans, except to the extent permitted under the 1940 Act.

4.   Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments, except to the extent permitted under the 1940 Act. This shall not prevent the Fund from investing in securities or other instruments backed by real estate, real estate investment trusts or securities of companies engaged in the real estate business.

5. Purchase or sell commodities or commodity contracts, except as permitted by the 1940 Act, as amended, and as interpreted or modified by the regulatory authority having jurisdiction from time to time

6. Underwrite securities issued by other persons, except to the extent permitted under the 1940 Act.

7. With respect to 75% of its total assets, purchase securities of an issuer (other than (i) securities issued by other investment companies, (ii) securities issued by the U.S. government, its agencies, instrumentalities or authorities, or (iii) repurchase agreements fully collateralized by U.S. government securities) if (a) such purchase would, at the time, cause more than 5% of the Fund’s total assets taken at market value to be invested in the securities of such issuer; or (b) such purchase would, at the time, result in more than 10% of the outstanding voting securities of such issuer being held by the Fund.

Group of related industries is defined as three or more industries based on the Adviser’s classification for the purpose of this section.

In addition to the foregoing fundamental investment policies, each Fund is also subject to the following non-fundamental restrictions and policies, which may be changed by the Board of Directors. Each Fund may not:

1. Acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments.

If a percentage limitation is adhered to at the time of investment or contract, a later increase or decrease in percentage resulting from any change in value or total or net assets will not result in a violation of such restriction, except that the percentage limitations with respect to the borrowing of money and illiquid investments will be observed continuously. If the percentage of the Fund’s net assets invested in illiquid investments exceeds 15% due to market activity or changes in the Fund’s portfolio, the Fund will take appropriate measures to reduce its holdings of illiquid investments as soon as reasonably practicable, in a manner consistent with prudent management and the interests of the Fund.

EXCHANGE LISTING AND TRADING

Shares are listed for trading and trade throughout the day on Nasdaq (the “Exchange”).

There can be no assurance that a Fund will continue to meet the requirements of the Exchange necessary to maintain the listing of shares. The Exchange will consider the suspension of trading in, and will initiate delisting proceedings of, the shares of a Fund under any of the following circumstances: (i) if any of the requirements set forth in the Exchange rules are not continuously maintained; (ii) if the Exchange files separate proposals under Section 19(b) of the 1940 Act and any of the statements regarding (a) the description of the Fund; (b) limitations on a Fund’s portfolio holdings or reference assets; (c) dissemination and availability of the intraday indicative values; or (d) the applicability of the Exchange listing rules specified in such proposals are not continuously maintained; (iii) if, following the initial 12-month period beginning at the commencement of trading of a Fund, there are fewer than 50 beneficial owners of shares of the Fund; (iv) if the intraday indicative value is no longer disseminated at least every 15 seconds during the Exchange’s regular market session and the interruption to the dissemination persists past the trading day in which it occurred; or (v) such other event shall occur or condition shall exist that, in the opinion of the Exchange, makes further dealings on the Exchange inadvisable. The Exchange will remove the shares from listing and trading upon termination of a Fund.

8

The Company reserves the right to adjust the price levels of its shares in the future to help maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of a Fund.

As in the case of other stocks traded on the Exchange, broker’s commissions on transactions will be based on negotiated commission rates at customary levels.

To provide additional information regarding the indicative value of shares, the Exchange or a market data vendor disseminates information every 15 seconds through the facilities of the Consolidated Tape Association, or other widely disseminated means, an updated “intraday indicative value” (“IIV”) for the Fund as calculated by an information provider or market data vendor. The Company is not involved in or responsible for any aspect of the calculation or dissemination of the IIVs and makes no representation or warranty as to the accuracy of the IIVs.

MANAGEMENT OF THE COMPANY

The business and affairs of the Company are managed under the oversight of the Board, subject to the laws of the State of Maryland and the Company’s Charter. The Directors are responsible for deciding matters of overall policy and overseeing the actions of the Company’s service providers. The officers of the Company conduct and supervise the Company’s daily business operations.

Directors who are not deemed to be “interested persons” of the Company (as defined in the 1940 Act) are referred to as “Independent Directors.” Directors who are deemed to be “interested persons” of the Company are referred to as “Interested Directors.” The Board is currently composed of seven Independent Directors and one Interested Director. The Board has selected Arnold M. Reichman, an Independent Director, to act as Chairman. Mr. Reichman’s duties include presiding at meetings of the Board and interfacing with management to address significant issues that may arise between regularly scheduled Board and Committee meetings. In the performance of his duties, Mr. Reichman will consult with the other Independent Directors and the Company’s officers and legal counsel, as appropriate. The Chairman may perform other functions as requested by the Board from time to time.

The Board meets as often as necessary to discharge its responsibilities. Currently, the Board conducts regular, in-person meetings at least four times a year, and holds special in-person or telephonic meetings as necessary to address specific issues that require attention prior to the next regularly scheduled meeting. The Board also relies on professionals, such as the Company’s independent registered public accounting firms and legal counsel, to assist the Directors in performing their oversight responsibilities.

The Board has established seven standing committees — Audit, Contract, Executive, Nominating and Governance, Product Development, Regulatory Oversight, and Valuation Committees. The Board may establish other committees, or nominate one or more Directors to examine particular issues related to the Board’s oversight responsibilities, from time to time. Each Committee meets periodically to perform its delegated oversight functions and reports its findings and recommendations to the Board. For more information on the Committees, see the section entitled “Standing Committees.”

The Board has determined that the Company’s leadership structure is appropriate because it allows the Board to effectively perform its oversight responsibilities.

Risk Oversight

The Board performs its risk oversight function for the Company through a combination of (1) direct oversight by the Board as a whole and Board committees and (2) indirect oversight through the Company’s investment advisers and other service providers, Company officers and the Company’s Chief Compliance Officer ("CCO"). The Company is subject to a number of risks, including but not limited to investment risk, compliance risk, operational risk, reputational risk, credit risk and counterparty risk. Day-to-day risk management with respect to the Company is the responsibility of the Company’s investment advisers or other service providers (depending on the nature of the risk) that carry out the Company’s investment management and business affairs. Each of the investment advisers and the other service providers have their own independent interest in risk management and their policies and methods of risk management will depend on their functions and business models and may differ from the Company’s and each other’s in the setting of priorities, the resources available or the effectiveness of relevant controls.

The Board provides risk oversight by receiving and reviewing on a regular basis reports from the Company’s investment advisers or other service providers, receiving and approving compliance policies and procedures, periodic meetings with the Company’s portfolio managers to review investment policies, strategies and risks, and meeting regularly with the Company’s CCO to discuss compliance reports, findings and issues. The Board also relies on the Company’s investment advisers and other service providers, with respect to the day-to-day activities of the Company, to create and maintain procedures and controls to minimize risk and the likelihood of adverse effects on the Company’s business and reputation.

Board oversight of risk management is also provided by various Board Committees. For example, the Audit Committee meets with the Company’s independent registered public accounting firms to ensure that the Company’s respective audit scopes include risk-based considerations as to the Company’s financial position and operations. The Board may, at any time and in its discretion, change the manner in which it conducts risk oversight. The Board’s oversight role does not make the Board a guarantor of the Company’s investments or activities.
