Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in preferred stocks and other preferred securities. Preferred stocks and preferred securities include, but are not limited to, convertible preferred securities, corporate hybrid securities, Trust Preferred Securities (defined below), cumulative and non-cumulative preferred stock, and depositary shares of preferred stock. Preferred securities generally pay fixed or adjustable-rate distributions to investors and have preference over common stock in the payment of distributions and the liquidation of a companys assets, but are generally junior to all forms of the companys debt, including both senior and subordinated debt.
