UPGR targets ESG companies involved in the production, generation, or distribution of green energy or in sustainable infrastructures that enable the use of renewable energy. The selection process starts with an initial universe comprising US stocks of all capitalizations. Eligible firms must meet size and liquidity requirements and have business exposure in the following industries: green mobility, green fuel, green energy, green wholesale power, environmental services, and pollution control, as classified by FactSet RBICS. The index applies exclusionary ESG screens to remove companies that are non-compliant with the UNGC principles, have an ESG risk score of 40 or higher, and are involved in controversial weapons, tobacco, thermal coal, oil and gas, and civilian firearms. From the remaining list, the fund selects the largest 50 securities by market-cap, with a maximum of 10 stocks per industry category. Holdings are weighted equally. The index rebalances on a quarterly basis.
