[2] Unlike the Fund, the MSCI AC World (Net) Index and the FTSE Global Infrastructure Opportunities Index are not investments, are not professionally managed and have no policy of sustainable investing. One cannot invest directly in any index.

[3] The FTSE Global Infrastructure Opportunities Index is designed to reflect the performance of infrastructure and infrastructure-related listed securities worldwide. Companies must derive a minimum of 20% of their revenue from either the core infrastructure activities or the infrastructure-related activities to be considered for index inclusion. The Index weights its constituents according to their investable market capitalization (after the application of free float and foreign ownership restrictions) in the index calculation. The FTSE Global Infrastructure Opportunities Index does not take account of ESG factors in its index construction.
