Strictly in accordance with its guidelines and mandated procedures, ICE Data Indices, LLC (the Index Provider) compiles and calculates the Underlying Index, which is a market capitalization-weighted index designed to track the performance of floating and variable rate investment grade and below investment grade U.S. dollar denominated preferred stock, as well as certain types of hybrid securities that are, in the judgment of the Index Provider, comparable to preferred stocks, that are issued by corporations in the U.S. domestic market. To be eligible for inclusion in the Underlying Index, the preferred stock or hybrid security must: (i) be publicly issued, (ii) be U.S.-registered or exempt from registration in the United States, (iii) have at least one day remaining to maturity and at least 18 months to maturity at the time of its issuance, (iv) be issued in either $25 or $1,000 par value increments, and (v) have a floating rate coupon or dividend, and must meet other minimum liquidity, trading volume and other requirements, as determined by the Index Provider. The Underlying Index may include fixed-to-floating rate preferred securities, which are securities that have an initial term with a fixed dividend rate and following this initial term bear a floating dividend rate. In general, preferred stock is a class of equity security that pays distributions to preferred stockholders. Preferred stockholders have priority over common stockholders in the payment of specified dividends, such that preferred stockholders receive dividends before any dividends are paid to common stockholders. In addition, preferred stock takes precedence over common stock in receiving proceeds from an issuer in the event of the issuers liquidation, but is generally junior to debt, including senior and subordinated debt. Although preferred stocks represent a partial ownership interest in a company, preferred stocks generally do not carry voting rights. Preferred stocks often have a liquidation value that equals the original purchase price of the stock at the time of issuance. Preferred stocks have economic characteristics similar to fixed-income securities; for example, preferred stocks generally pay dividends at a specified rate, which may be fixed or variable. Variable- or floating-rate preferred stocks pay dividends at rates that adjust periodically according to formulae intended generally to reflect market rates of interest, float at a fixed margin above a generally recognized base lending rate, or are reset or re-determined on specified dates (such as the last day of a month or calendar quarter). Dividends may be paid on a variable rate percentage of the fixed par value at which the preferred stock is issued. Hybrid securities that are comparable to preferred stock are those securities that, like traditional preferred stock, have preference over the common stock within an issuers capital structure, and are issued and traded in a similar manner to traditional preferred stock. Like preferred stock (but unlike debt securities or common stock), hybrid securities have the ability to defer dividend payments to stockholders and to extend their maturity dates to different durations. The Underlying Index may include securities of large-, mid- and small-capitalization companies. As of October 31, 2025, the Underlying Index was comprised of 321 constituents. The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a sampling methodology to seek to achieve its investment objective. The Fund is non-diversified and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the 1940 Act). Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of August 31, 2025, the Fund had significant exposure to the financials sector. The Funds portfolio holdings, and the extent to which it concentrates its investments, are likely to change over time. Show less
