BLLD is designed to provide long-term capital appreciation by investing in companies developing the infrastructure required to facilitate a sustainable and inclusive economy. Invests primarily in common stocks and depositary receipts that are facilitating access to essential goods and services, improved connectivity, social infrastructure, and environmental resilience. Uses a “thematic” investment approach that seeks to identify and invest in companies that are relevant to sustainable infrastructure. Selects companies within key sub-themes, such as electricity infrastructure, renewables infrastructure, transport infrastructure, water infrastructure, digital infrastructure, sustainable logistics, medical infrastructure, social housing, and education infrastructure.
