The Fund will, under normal circumstances, invest at least 80% of its total assets in securities of the Index. The Index is designed to track the performance of companies that derive at least 50% of their revenue and/or assets from mining, exploration, development, or production of lithium. The Index generally consists of from 40 to 50 constituents. This investment policy may be changed without shareholder approval, upon 60 days notice to shareholders. The universe of eligible index components includes exchange-listed equity securities of companies that have or expect to have a significant portion of their business operations related to lithium. Such companies are identified through the use of a proprietary selection methodology that may include a review of industry publications, sell side research, and fundamental research, as well as meetings with management.
