This exchange-traded fund (ETF) aims to replicate, before the deduction of fees and expenses, the performance of the Bloomberg Barclays MSCI US Corporate Sustainability SRI Sector/Credit/Maturity Neutral Index. To achieve this objective, the fund typically allocates a substantial majority of its total assets, at least 80%, to the specific securities that constitute its benchmark index. The underlying benchmark index is designed to largely preserve the broad characteristics of its foundational index, the Bloomberg Barclays US Corporate Index, which represents a universe of high-quality corporate debt.
