This exchange-traded fund (ETF) aims to replicate the investment performance, before accounting for fees and expenses, of the S&P High Income Infrastructure Index. To achieve its objective, the fund allocates a minimum of 90% of its total assets to the securities comprising this underlying index, including American Depositary Receipts (ADRs) and Global Depositary Receipts (GDRs) representing those index constituents. The S&P High Income Infrastructure Index is constructed to measure the returns of 50 high-yielding global equity securities issued by companies operating across various infrastructure-related sectors.
