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 Indxx Global Natural Resources Income Index. The fund will normally invest at least 90% of its net assets (including investment borrowings) in common stocks and/or depositary receipts that comprise the index. The index is a 50-stock free float adjusted market capitalization weighted index designed to measure the market performance of the 50 highest dividend yielding companies involved in the upstream segment of the natural resources sector. The fund is non-diversified.
