Investment Risk. As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.

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

Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV, and there may be times when the market price of the shares is more than the NAV (premium) or less than the NAV (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Cash Redemption Risk. The Fund generally redeems shares for cash or otherwise includes cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments in order to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Counterparty and Issuer Credit Risk. The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations or cause such issuer or counterparty to be perceived (whether by market participants, rating agencies, pricing services or otherwise) as being in such situations. The value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults, changes in the credit ratings of the Fund’s portfolio investments and/or perceptions related thereto.

Derivatives Risk. The Fund will invest in derivatives, including as a substitute to gain short exposure to U.S. Treasuries. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as

a commodity, index, interest rate or inflation rate. The return on a derivative instrument may not correlate with the return of its underlying reference asset. Derivatives are subject to a number of risks described elsewhere in the Fund’s Prospectus, such as market risk and issuer-specific risk. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. In addition to the other risks associated with the use of derivatives described elsewhere in this Prospectus, there are risks associated with the Fund’s use of futures contracts. With respect to futures contracts and short exposure through futures contracts, these risks include but are not limited to: (1) the success of the adviser’s and sub-adviser’s ability to predict movements in the prices of individual securities, fluctuations in markets and movements in interest rates; (2) an imperfect or no correlation between the changes in market value of the securities and the prices of futures contracts; and (3) no guarantee that an active market will exist for the contracts at any particular time. In addition, while the Fund may short securities such as U.S. Treasuries, the Fund’s anticipated short exposure through derivative instruments may lead to less correlation with the Index.

Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments.

Hedging Risk. The Index seeks to mitigate the potential negative impact of rising U.S. Treasury rates on the performance of bonds in the long portfolio of the Index. The Index’s short positions in U.S. Treasuries, as well as the Fund’s holdings to obtain such exposure, are not intended to mitigate credit risk or mitigate changes in bond values associated with investor perceptions regarding, or premiums placed on, credit risk (i.e., credit risk premiums) or otherwise mitigate risks associated with other factors influencing the price of such bonds, which may have a greater impact than rising or falling interest rates. There is no guarantee that the short positions will completely eliminate the interest rate risk of the long bond positions. The Index’s short positions also may fail to provide the targeted duration in light of changes in the shape of the U.S. Treasury curve. The interest rate profile between the long and short exposures of the Index and Fund could also evolve significantly between monthly rebalancing. This could lead to temporary dislocations between the Fund’s intended and actual sensitivity to interest rates, which could impact performance. There may also be significant differences between the bond markets and U.S. Treasury markets (including futures markets for U.S. Treasuries) that could result in the Fund’s short positions performing ineffectively, exacerbating losses or causing greater tracking error. In addition, when interest rates fall, an unhedged investment in the same long portfolio of bonds will outperform the Fund.

High Yield Securities Risk. Higher yielding, high risk debt securities, sometimes referred to as junk bonds, may present additional risk because these securities may be less liquid and present more credit risk than investment grade bonds. The price of high yield securities tends to be more susceptible to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Interest Rate Risk. Interest rate risk with respect to the Fund is the risk that short exposure to fixed income securities will decline in value because of decreases in interest rates.

Investment Style Risk. The Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. The Fund does not attempt to outperform its Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index.

Issuer-Specific Risk. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.

Non-Correlation Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons.

Non-Diversification Risk. The Fund will be considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Portfolio Turnover Risk. The Fund’s investment strategy may result in a high portfolio turnover rate. High portfolio turnover would result in correspondingly greater transaction expenses and may result in the distribution to shareholders of additional capital gains for tax purposes. These factors may negatively affect the Fund’s performance.

Short Sales Risk. The Fund will engage in “short sale” transactions. The Fund will lose value if the security or instrument that is the subject of a short sale increases in value. The Fund may enter into short positions in U.S. Treasuries as well as short derivative positions through futures contracts on U.S. Treasuries. If the price of the security or derivative that is the subject of a short sale increases, then the Fund will incur a loss equal to the increase in price from the time that

the short sale was entered into plus any premiums and interest paid to a third party in connection with the short sale. The risk of loss on a shorted position is potentially unlimited unlike the risk of loss on a long position, which is limited to the amount paid for the investment plus transaction costs. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund. Further, in times of unusual or adverse economic, market or political conditions, neither the Index nor the Fund may be able to fully or partially implement its short selling strategy.

U.S. Treasury Exposure Risk. The methodology used to select U.S. Treasuries (or U.S. Treasuries or U.S. Treasury futures, in the case of the Fund) for different maturities within the short exposure could produce performance that is dissimilar from other U.S. Treasuries of similar maturities. For example, unique supply and demand conditions could create a market whereby selected U.S. Treasuries or positions trade either more or less expensively than other U.S. Treasuries or positions of the same maturity, which could negatively impact the performance of the Fund.

Yield Curve Risk. The Index and Fund will have short exposure to U.S. Treasuries with different maturity dates and weightings. Interest rates do not change uniformly for U.S. Treasuries of differing lengths of maturity in response to market and economic conditions. For example, interest rates for shorter maturity U.S. Treasuries may rise or fall more or less than interest rates for longer maturity U.S. Treasuries and rates may rise for U.S. Treasuries of certain maturities but fall for U.S. Treasuries of different maturities. Changes in interest rates among U.S. Treasuries with different maturities could impact returns produced both by the long exposures and short exposures of the Index and Fund in different ways, which could lead to unexpected performance. The methodology of the Index and the investment approach of the Fund seek to address this risk, but are subject to the constraints of providing the desired overall interest rate profile and evolving market conditions, and there is no guarantee that any such risk will be reduced or the desired outcome will occur.
