The First Trust Japan AlphaDEX® Fund is an exchange-traded fund. The investment objective of the Fund is to seek investment results that correspond generally to the price and yield, before the Fund's fees and expenses, of an equity index called the NASDAQ AlphaDEX® Japan Index. Nasdaq constructs the NASDAQ AlphaDEX® Japan Index by ranking the eligible stocks from the NASDAQ Japan Index on growth factors including 3-, 6- and 12- month price appreciation, sales to price and one year sales growth, and separately on value factors including book value to price, cash flow to price and return on assets. All stocks are ranked on the sum of ranks for the growth factors and, separately, all stocks are ranked on the sum of ranks for the value factors. A stock must have data for all growth and/or value factors to receive a rank for that style.
