There is no guarantee that ABXB will achieve its investment objective. Investing involves risk, including the possible loss of principal. Because the Fund is an ETF (rather than a mutual fund), shares are bought and sold at market price (not NAV), may trade at a discount or premium to NAV, and are not individually redeemable. Owners of the shares may acquire those shares from the Fund and tender those shares for redemption to the Fund in Creation Unit aggregations only, consisting of 25,000 shares. Brokerage commissions will reduce returns.

Investments in the Fund include risks associated with small-and mid-cap securities, which involve limited liquidity and greater volatility than large-cap securities. Because the Fund invests in ETFs, an investor will indirectly bear the principal risks of the underlying funds, including illiquidity, and an investment in the Fund will entail more costs and expenses than a direct investment in the Underlying ETFs.

The Fund may participate in futures markets, which are highly volatile, and the use of futures may increase the volatility of the Fund’s NAV. Investments in debt securities typically decrease in value when interest rates rise. This risk is usually greater for longer-term debt securities. Investments by the Fund in high yield securities and unrated securities of similar credit quality are considered to be speculative and are generally subject to a greater risk of loss of principal and interest than investment grade securities. Investment in a fund that utilizes a tactical overlay that seeks to minimize risk may not be appropriate for every investor seeking a particular risk profile. Active and frequent trading of portfolio securities may result in increased transaction costs to the Fund, and may also result in higher taxes if Shares are held in a taxable account.

Index-Based Strategy Risk. Passive funds that seek to track an index may hold the component securities of the underlying index regardless of the current or projected performance of a specific security or relevant market as a whole, which could cause the Fund returns to be lower than if the Fund employed an active strategy. The performance of the Fund may diverge from that of its Index.
