Under normal market conditions, the Fund will invest at least 80 percent of its net assets (including investment borrowings) in the equity securities of companies identified by the Funds investment sub-advisor, Energy Income Partners, LLC (EIP or the Sub-Advisor), as having or seeking to have a positive carbon impact. The Sub-Advisor defines positive carbon impact companies as companies that reduce, have a publicly available plan to reduce, or enable the reduction of carbon and other greenhouse gas (GHG) emissions from the production, transportation, conversion, storage and use of energy. The companies in which the Fund invests will have demonstrated a commitment to positive carbon impact activities, as determined by the Sub-Advisor, based on its fundamental research and review of public documents, such as regulatory filings and investor and public communications. Examples of positive carbon impact activities include investing capital in activities and technologies with lower GHG emissions, such as wind and solar power generation, or by replacing coal fired power generation facilities with natural gas power generation facilities.
