UNIY seeks comprehensive exposure to the USD bond market while enhancing yield within risk parameters and constraints. The index deconstructs the USD bond market into five segments, where the core component is US investment grade debt. The non-core segments are US restricted securities, Eurodollar debt, US corporate high-yield debt, and emerging market debt. The index weights the resulting portfolio in tiers. All non-core segments are weighted based on market value. The core segment is split in half, such that 50% weight is assigned to the Bloomberg US Aggregate Bond Index. The other 50% is allocated according to the yield-enhanced methodology of the Bloomberg US Aggregate Enhanced Yield Index. This weighting is designed to earn greater yield while maintaining a similar risk profile to the broader US investment grade debt universe. UNIY uses a sampling strategy to track its index, which rebalances monthly.
