The investment seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Barclays US Floating Rate Note < 5 Years Index (the "underlying index"). The underlying index measures the performance of U.S. dollar-denominated, investment grade floating rate notes. The fund generally invests at least 90% of its assets in the securities of the underlying index and in investments that provide substantially similar exposure to the securities in the underlying index. The fund is non-diversified.
