This fund's underlying index is designed to mirror the financial outcomes of companies located in developed markets that are significantly involved in the international clean energy industry. At least 80% of its total net assets are committed to various financial instruments, such as swap agreements, the actual securities comprising the index, and exchange-traded funds (ETFs) that replicate the index. It also utilizes other financial tools intended to offer daily leveraged exposure to either the benchmark index itself or ETFs that track it.
