BHYB focuses on the top two tiers of the junk bond market segment. The fund consists of corporate bonds with credit ratings ranging from Ba1/BB+ to B3/B-. Companies, whether U.S.-based or international, have the flexibility to issue these bonds, provided that they are denominated in USD. Eligible debt securities are issued by companies exposed to risk in FX-G10 member countries and have at least one year remaining until maturity. Additionally, only those with an option spread of less than 10% are included. The Underlying Index is market value-weighted with a maximum 2% allocation per issuer, and any surplus weight is allocated proportionally to the other qualifying issuers. However, in cases where there are fewer than 50 bonds qualify for inclusion, the holdings will be equally weighted. The index excludes those tied to the financial sector. The fund may enter lending transactions. The securities in the Underlying Index are rebalanced on the last calendar day of each month.
