|First Trust DevMkts exUS SC AlphaDEXETF|
|The investment seeks investment results that correspond generally to the price and yield (before the fund's fees and expenses) of an equity index called the Defined Developed Markets ex-US Small Cap Index.
The fund will normally invest at least 90% of its net assets in common stocks and/or depositary receipts that comprise the index. The index is a modified equal-dollar weighted index calculated by SPDJI based on select small cap securities from the S&P Developed Markets ex-US BMI Index that may generate positive alpha relative to traditional passive-style indices through the use of the AlphaDEX(R) selection methodology. It is non-diversified.|
