The investment seeks to track as closely as possible, before fees and expenses, the total return of the Dow Jones U.S. Select REIT IndexSM. The fund invests at least 90% of its net assets in securities included in the index. It generally gives the same weight to a given security as the index does. The index is a float-adjusted market capitalization weighted index comprised of real estate investment trusts ("REITs"). The fund may sell securities that are represented in the index in anticipation of their removal from the index, or buy securities that are not yet represented in the index in anticipation of their addition to the index. It is non-diversified.
