FIRST TRUST NATURAL GAS ETF

The First Trust Natural Gas ETF 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 fees and expenses, of an equity index called the ISE-Revere Natural Gas™ Index. The Index is constructed by establishing the universe of U.S. listed stocks of companies involved in the exploration and production of natural gas. Companies whose natural gas proved reserves do not meet certain requirements are eliminated.
