In February 2021, the First Trust AlphaDEX™ U.S. Energy Sector Index ETF (the "First Trust ETF") changed its investment objectives to seek to replicate, to the extent possible, the performance of an index of U.S. companies that have devoted or have committed to devote, material resources to the research, development and application of fifth generation and next generation digital cellular technologies as they emerge, initially the Indxx 5G & NextG Thematic Index^SM. In connection with the change of investment objectives, the name of the First Trust ETF changed to First Trust Indxx NextG ETF. The First Trust ETF provides exposure to its new index by investing all or substantially all of its assets in an underlying U.S. index fund known as First Trust Indxx NextG ETF, which is managed by the First Trust ETF's portfolio advisor. The effective date of change is February 17, 2021.
