The objective of the Fund is to track the performance of the U.S. inflation-linked government bond market (otherwise known as Treasury Inflation Protected Securities, or TIPS). The Fund seeks to track the performance of the Bloomberg U.S. Government Inflation-Linked Bond Index (the Index) as closely as possible. The Fund invests primarily in securities included in the Index. These securities includes U.S. inflation-linked investment grade (high quality), or higher, government bonds. In seeking to track the performance of the Index the Fund will use a stratified sampling strategy to build a representative portfolio.
