The fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in below-investment-grade (commonly known as "junk" or "high yield") fixed-income securities, such as bonds and bank loans. The fund invests in U.S. treasury securities, investment grade bank loans (also known as senior floating rate interests), and preferred securities.
