The Invesco MSCI Sustainable Future ETF (ERTH) is an exchange-traded fund structured to mirror the performance of the MSCI Global Environment Select Index. To achieve its investment objective, the Fund generally dedicates at least 90% of its total assets to the specific securities that constitute this benchmark index. The underlying Index is composed of companies distinguished by their focus on developing products or delivering services that foster a more environmentally sound global economy. These companies contribute to this goal by promoting the more efficient use of the world's resources. The design of the Index emphasizes significant exposure to six key environmental impact areas: alternative energy solutions, enhancements in energy efficiency, sustainable building practices, responsible water management, measures for pollution prevention and control, and sustainable agricultural techniques. Both the Fund and the Index are reviewed and rebalanced every three months.
