The investment seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of the iBoxx 3-Year Target Duration TIPS Index. The underlying index reflects the performance of a selection of inflation protected public obligations of the U.S. treasury, commonly known as TIPS, with a targeted average modified adjusted duration, as defined by the index provider, of approximately three years. Under normal circumstances, the fund will invest at least 80% of its total assets (exclusive of collateral held from securities lending) in the securities of the underlying index. The fund is non-diversified.
