The investment seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Barclays U.S. Treasury Inflation-Protected Securities (TIPS) 0-5 Years Index (Series-L) (the "underlying index"). The fund generally invests at least 90% of assets in the bonds of the underlying index and at least 95% of assets in U.S. government bonds. The underlying index measures the performance of the inflation-protected public obligations of the U.S. Treasury that have a remaining maturity of less than five years.
