Tortoise Global Water Index℠ (TGWTR)

The Tortoise Global Water Index℠ is a proprietary, rules-based, modified capitalization-weighted, float-adjusted index comprised of companies that are materially engaged in the water infrastructure or water management industries.

Overview

Water is an essential asset — critical to economic growth and social stability. The companies that manage, treat, and distribute water are vital not only to our survival, but also our ability to thrive and prosper. Significant investment must be made to maintain our current infrastructure and to develop new infrastructure to more sustainably utilize and distribute this vital resource

We believe that the Tortoise Global Water Index℠ is comprised of companies that represent the current global water landscape, make conscientious efforts to positively impact the world, and are poised to participate and benefit from growth in the water industry. We consciously strives to maximize our positive impact by holding the constituent companies to high standards of positive impact as well.
