iShares MSCI Water Management Multisector ETF(NASDAQ:IWTR)

IWTR concentrates on companies that address and contribute to global water scarcity management. Starting with a broad investable universe, the fund applies exclusionary screens to remove companies that are: engaged in certain business industries such as tobacco, involved in very severe ESG controversies, and/or are in the bottom 25% of the environmental pillar and water stress management score of the MSCI ESG Ratings framework. The fund also excludes firms that are deemed misaligned with the UN Sustainable Development Goals. The remaining companies are then categorized into two equally weighted subsets: 1) Water Supply Universe includes firms that provide exposure to water-focused products or services and derive at least 10% of their revenues from sustainable water, and 2) Water Usage Universe consists of companies that demonstrate relatively efficient water management. Securities within each universe are weighted by market-cap. The index is reconstituted and rebalanced semi-annually.
