The First Trust Indxx Innovative Transaction & Process ETF (LEGR) aims to replicate the total returns, before deducting its fees and expenses, of the Indxx Blockchain Index. To achieve this, the Fund typically allocates at least 90% of its net assets, including any borrowed funds, to the common equities and depositary receipts that constitute this underlying index. The Indxx Blockchain Index itself is crafted to monitor the progress of companies significantly involved with distributed ledger technology (blockchain).
