The fund seeks to achieve its investment objective by investing at least 80% of its net assets in securities included in the index. The rules-based index is comprised of constituents that are a blend of allocations to two asset classes: unaffiliated U.S. high yield corporate bond (or “junk bond”) exchange-traded funds (“ETFs”) and unaffiliated U.S. 3-7 year Treasury ETFs. The index also includes a stop loss mechanism on the U.S. 3-7 year Treasury ETFs that allows the index to invest in U.S. T-bill ETFs.
