The index is designed to offer exposure consistent with the total return of U.S. investment-grade aggregate bonds, without receiving and reinvesting dividend income, by investing in ETFs. Under normal market conditions, F/m Investments LLC (the “Adviser”) seeks to achieve the fund’s objective by investing at least 80% of the fund’s net assets (plus any borrowings for investment purposes) in underlying funds that primarily invest in U.S. dollar denominated investment-grade bonds.
