As with all ETFs, Shares may be bought and sold in the secondary market at market prices. 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.

Fund Risks: 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. 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).

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.

Average Yield to Maturity is the discount rate that equates the present value of a bond’s cash flows with its market price (including accrued interest). The Fund Average Yield to Maturity is the weighted average of the fund’s individual bond holding yields based on Net Asset Value (‘NAV’). The measure does not include fees and expenses. For callable bonds, this yield is the yield-to-worst.

Effective Duration measures the sensitivity of the price of a bond with or without embedded options to changes in interest rates, taking into account the likelihood of the bond being called, put and/or sunk prior to its final maturity date while incorporating after-tax impacts on the bond.

Premium/Discount is the amount the fund’s closing price is trading above or below the reported NAV, expressed as a percentage of the NAV. When the fund’s closing price is greater than the fund’s NAV, it is said to be trading at a “premium” and the percentage is expressed as a positive number. When the fund’s closing price is less than the fund’s NAV, it is said to be trading at a “discount” and the percentage is expressed as a negative number.

Median 30 day spread is calculated by identifying the national best bid and national best offer (“NBBO”) for each fund as of the end of each 10 second interval during each trading day of the last 30 calendar days and dividing the difference between each such bid and offer by the midpoint of the NBBO. The median of those values is identified and that value is expressed as a percentage rounded to the nearest hundredth.

Weighted average maturity is the average length of time to the repayment of principal for the securities in the fund. This metric considers the likelihood that bonds will be called or prepaid before the scheduled maturity date.

Duration is a measure of the sensitivity of the price of a bond or other debt instrument to a change in interest rates.

Investments involve risk. Principal loss is possible.
