This ETF, known as the iShares ESG Aware U.S. Aggregate Bond ETF, endeavors to replicate the performance of an underlying index. This index is constructed from a selection of high-quality, U.S. dollar-denominated debt securities. These securities originate from issuers specifically chosen for their positive environmental, social, and governance (ESG) conduct. The fund's overall strategy is to closely mirror the risk and return profile of the wider U.S. dollar-denominated investment-grade bond market.
