Income.

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. You may also incur other fees, such as usual and customary brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and the Example that follows.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Under normal market conditions, the Fund invests at least 80% of its net assets in direct obligations of the U.S. Treasury, including Treasury bonds, bills, notes and Treasury Inflation-Protected Securities (TIPS), and investments that provide exposure to direct obligations of the U.S. Treasury. Derivatives that provide exposure to U.S. Treasuries may be used to satisfy the Fund’s 80% policy. The Fund may invest in U.S. Treasury securities of any maturity and intends to primarily focus on U.S. Treasury securities with a remaining maturity of between 1-30 years.

The Fund may also invest in securities issued or guaranteed by the U.S. government, its agencies, or instrumentalities, including government sponsored entities and mortgage-backed securities.

A mortgage-backed security is an interest in a pool of mortgage loans made and packaged or “pooled” together by banks, mortgage lenders, various governmental agencies and other financial institutions for sale to investors to finance purchases of homes, commercial buildings and other real estate. The Fund’s investments in mortgage-backed securities include securities that are issued or guaranteed by the U.S. government, its agencies or instrumentalities, which include mortgage pass-through securities representing interests in “pools” of mortgage loans issued or guaranteed by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), and the Federal Home Loan Mortgage Corporation (Freddie Mac). The mortgage securities the Fund invests in may be fixed-rate or adjustable-rate mortgage-backed securities (ARMS).

The Fund may also purchase or sell mortgage securities on a delayed delivery or forward commitment basis through the “to-be-announced” (TBA) market. With TBA transactions, the particular securities to be delivered must meet specified terms and conditions.

To pursue its investment goal, the Fund may enter into certain interest rate-related derivative transactions, principally interest rate/bond and U.S. Treasury futures contracts and interest rate swaps. The use of these derivative transactions may allow the Fund to obtain net long or short exposures to select interest rates or durations. These derivatives may be used to enhance Fund returns, increase liquidity, gain exposure to certain instruments or markets in a more efficient or less expensive way and/or hedge risks associated with its other portfolio investments.

The investment manager generally buys, and holds, high quality fixed income securities. Using this straightforward approach, the investment manager seeks to

produce current income with a high degree of credit safety from a conservatively managed portfolio of U.S. Treasury securities. The investment manager may utilize quantitative models to evaluate investment opportunities as part of the portfolio construction process for the Fund. Quantitative models are proprietary systems that rely on mathematical computations to identify investment opportunities. The investment manager may consider selling a security when it believes the security has become fully valued due to either its price appreciation or changes in the issuer’s fundamentals, or when the investment manager believes another security is a more attractive investment opportunity.

Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest, inflation or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in additional tariffs, trade barriers and/or investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economic prospects of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.

Mortgage Securities: Mortgage securities differ from conventional debt securities because principal is paid back periodically over the life of the security rather than at maturity. The Fund may receive unscheduled payments of principal due to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. Because of prepayments, mortgage securities may be less effective than some other types of debt securities as a means of "locking in" long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. A reduction in the anticipated rate of principal prepayments, especially during periods of rising interest rates, may increase or extend the effective maturity and duration of mortgage securities, making them more sensitive to interest rate changes, subject to greater price volatility, and more susceptible than some other debt securities to a decline in market value when interest rates rise.

Prepayment: Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.

When-Issued and Delayed Delivery Transactions: Mortgage-backed securities may be issued on a when-issued or delayed delivery basis, where payment and delivery take place at a future date. Because the market price of the security may

fluctuate during the time before payment and delivery, the Fund assumes the risk that the value of the security at delivery may be more or less than the purchase price.

Inflation-Indexed Securities: Inflation-indexed securities have a tendency to react to changes in real interest rates. Real interest rates represent nominal (stated) interest rates lowered by the anticipated effect of inflation. In general, the price of an inflation-indexed security decreases when real interest rates increase, and increases when real interest rates decrease. Interest payments on inflation-indexed securities will fluctuate as the principal and/or interest is adjusted for inflation and can be unpredictable. Any increase in the principal amount of an inflation-protected debt security will be considered taxable ordinary income, even though investors, such as the Fund, do not receive their principal until maturity.

Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, authorized participants, or index providers (as applicable) and listing exchanges, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in

financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

Portfolio Turnover: Active and frequent trading may increase a shareholder’s tax liability and the Fund’s transaction costs, which could detract from Fund performance.

Authorized Participant Concentration: Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. "Authorized Participants" are broker-dealers that are permitted to create and redeem shares directly with the Fund and who have entered into agreements with the Fund’s distributor. The Fund has a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined below), Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting. This risk may be more pronounced in volatile markets, potentially where there are significant redemptions in ETFs generally.

Large Shareholder: Certain large shareholders, including other funds or accounts advised by the investment manager or an affiliate of the investment manager, may from time to time own a substantial amount of the Fund’s shares. In addition, a third-party investor, the investment manager or an affiliate of the investment manager, an authorized participant, a lead market maker, or another entity may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.
