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 fund invests at least 80% of its total assets in the securities of the underlying 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 underlying index, of approximately three years. It may also invest up to 20% of its assets in cash and cash equivalents. The fund is non-diversified.
