The fund seeks to track the investment results of an index composed of U.S. dollar-denominated, high yield corporate bonds.

The fund seeks to track the investment results of the ICE BofA US High Yield Constrained Index (the “Underlying Index”), which is a rules-based index consisting of U.S. dollar-denominated, high yield (as determined by ICE Data Indices, LLC (“Index Provider”)) corporate bonds publicly issued and settled in the U.S. The Underlying Index is designed to provide a broad representation of the U.S. dollar-denominated high yield corporate bond market. The Underlying Index is a modified market value-weighted index with a cap on each issuer of 2%. There is no limit to the number of issues in the Underlying Index, but as of October 31, 2024, the Underlying Index included approximately 1,875 constituents and the issuers in the Underlying Index are principally located in the U.S. The components of the Underlying Index are likely to change over time.

As of February 28, 2025, the bonds eligible for inclusion in the Underlying Index include U.S. dollar-denominated high yield corporate bonds that: (i) are issued by companies having “risk exposure” to countries (i.e., issuers that are subject to the risks of one or more of these countries as a result of the principal country of domicile of the issuers (as determined by the Index Provider)) that are members of the FX-G10, which include Australia, Austria, Belgium, Canada, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Japan, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, New Zealand, Norway, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, the U.K. and the U.S. and their respective territories; (ii) have an average rating of below investment grade (ratings from Fitch Ratings, Inc., Moody’s Investors Service, Inc. or S&P Global Ratings are considered; if more than one agency provides a rating, the average rating is attached to the bond); (iii) are registered with the SEC, exempt from registration at issuance, or offered pursuant to Rule 144A under the Securities Act of 1933, as amended, with or without registration rights; (iv) have at least $250 million of outstanding face value; (v) have an original maturity date of at least 18 months; and (vi) have at least one year to maturity. Excluded from the Underlying Index are certain hybrid capital securities, securities issued or marketed primarily to retail investors, equity-linked securities, securities in legal default, hybrid securitized corporates, eurodollar bonds, taxable and tax-exempt US municipal securities and $1000 par preferred and dividends received deduction-eligible securities.
