DRLL attempts to use the power of shareholder engagement and proxy voting to influence energy companies. The issuer believes there is an opportunity for energy companies to focus on solving global demand for energy and abandon political agendas, specifically ESG-imposed constraints. The fund is passively managed, providing exposure to oil and gas producers in the US equity market. From a starting universe of 1500 US-listed firms, the fund selects companies in the energy industry or sector specifically involved in oil and gas exploration, production, refinement, and marketing, including integrated oil companies. Constituents are free float-adjusted market cap-weighted with single issuers capped at 22.5%, and the aggregate weight of all issuers that individually exceed 4.5% of the portfolio capped at 45%. The index is reconstituted semi-annually and is rebalanced quarterly. Prior to April 11, 2024, the fund tracked the Solactive United States Energy Regulated Capped Index TR.
