The Fund generally invests at least 80% of its total assets in the constituents of the Index. The Index is designed to measure the performance of an investable universe of fixed income securities of varying credit quality and duration, including corporate bonds, lower-quality bonds, known as high yield or junk bonds, treasury bonds, municipal bonds, mortgage backed securities and convertible bonds, that provide broad exposure to the U.S. and global bond market. The Index has approximately 12 ETF constituents which are weighted differently throughout the phases of the economic cycle (i.e., expansion, peak, contraction, trough) in an effort to maximize risk-adjusted returns. The Index may have up to 12.5% in an alternative sleeve of instruments that could range from currency ETFs to commodity ETFs. The Fund will not invest more than 15% of its net assets in illiquid securities.
