The Fund is an actively-managed exchange-traded fund (ETF) that, under normal market conditions, invests at least 80 percent of its net assets (plus the amount of any borrowings for investment purposes) in a portfolio of preferred and debt securities that, at the time of issuance, are eligible to pay dividends that qualify for favorable U.S. federal income tax treatment. It is expected that such dividends will include qualified dividend income (QDI) and qualified dividends from REITs (QRD). The types of preferred and debt securities in which the Fund invests will include fixed rate preferred securities, variable rate preferred securities, REIT preferred securities, floating rate preferred securities, bond equivalent preferred securities, convertible preferred securities, contingent convertible securities, and other capital securities issued by financial institutions and corporate issuers for purposes of equity capital credit from Nationally Recognized Statistical Rating Organizations, and various types of junior subordinated debt.
