The investment seeks to track the investment results of the Bloomberg Barclays U.S. Treasury Inflation-Protected Securities (TIPS) 0-5 Years Index (Series-L). The fund generally will invest at least 90% of its assets in the component securities of the underlying index and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents. The index measures the performance of the inflation-protected public obligations of the U.S. Treasury, commonly known as TIPS, that have a remaining maturity of less than five years.
