The Fund seeks to track the investment results of the FTSE EPRA Nareit Developed Green Target Index (the Underlying Index), which was developed by FTSE International Limited (the Index Provider or FTSE). The Underlying Index is composed of securities selected from the FTSE EPRA Nareit Developed Index (the Parent Index). The Parent Index is composed of real estate investment trusts (REITs) and real estate holding and development companies from developed market countries or regions. The Underlying Index reweights constituents of the Parent Index to target, in aggregate, a minimum level of green certification; an increase in green certification and a reduction in energy usage, both relative to the Parent Index; and a level of carbon emission intensity that is no worse than that of the Parent Index, subject to certain constraints. The Parent Index may include large-, mid- and small-capitalization constituents.
