[1] The Bloomberg US Aggregate Bond Index is a broad-based benchmark that measures the investment-grade, U.S. dollar-denominated, fixed-rate taxable bond market.
[2] Bloomberg US Corporate High Yield 2% Issuer Capped Index is an issuer-constrained version of the Bloomberg US Corporate High Yield Index that measures the market of USD-denominated, noninvestment-grade, fixed-rate, taxable corporate bonds. The index follows the same rules as the uncapped index but limits the exposure of each issuer to 2% of the total market value and redistributes any excess market value index-wide on a pro rata basis.
