| Investment Objective: |
iShares 1-10 Year U.S. Aggregate Bond ETF seeks to track the investment results of an index composed of U.S. dollar-denominated investment-grade bonds with remaining effective maturities primarily between one and ten years. The Fund seeks to track the investment results of the Bloomberg Intermediate US Aggregate Index, which is a subset of the Bloomberg US Aggregate Index. The Underlying Index measures the performance of certain U.S. dollar-denominated fixed-rate bonds that are rated investment grade, as determined by Bloomberg Index Services Limited. Non-securitized bonds included in the Underlying Index must have greater than one year and less than 10 years until final maturity, but this maturity constraint is not applied for securitized bonds included in the Underlying Index. The remaining effective maturity of a securitized instrument is measured using weighted average life ("WAL") i.e., the average length of time that each dollar of unpaid principal remains outstanding. The remaining effective maturity of most securitized instruments included in the Underlying Index, as measured by WAL, historically has been 1-10 years, including due to prepayments of principal. |
