The fund aims to mirror the performance of an index comprising BBB-rated, U.S. dollar-denominated corporate bonds. These securities are fixed-rate and taxable, issued by industrial, utility, and financial corporations situated both within and outside the United States. Typically, at least 80% of the ETF's net assets are allocated, either directly or indirectly, to a collection of such investment-grade corporate debt instruments. A key characteristic of these bonds is their BBB rating and a remaining maturity period of a decade or more. It's worth noting that this fund employs a non-diversified investment strategy.
