The investment seeks investment results that correspond generally to the price and yield (before the fund’s fees and expenses) of an index called the Alerian Disruptive Technology Real Estate Index. The fund will normally invest at least 90% of its net assets (plus any borrowings for investment purposes) in the common stocks, real estate investment trusts (“REITs”) and depository receipts that comprise the index. The index seeks to provide exposure to companies that own, operate and/or lease real estate that supports advanced wired and wireless communication, data storage and processing infrastructure, e-commerce warehouses and fulfillment centers.
