The fund seeks to track the investment results of the Bloomberg Barclays U.S. Treasury Inflation-Protected Securities (TIPS) 0-5 Years Index (Series-L) (the Underlying Index), which 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. TIPS are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the non-seasonally adjusted Consumer Price Index for All Urban Consumers (CPI), and TIPS principal payments are adjusted according to changes in the CPI.
