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'). It aims to do this by tracking the Barclays US Government Inflation-Linked Bond Index. The Index measures the performance of the U.S. treasury inflation-linked bond market. Securities must be rated investment grade as defined by the Index methodology. The principal and the interest of all constituent bonds must be inflation-linked and denominated in U.S. Dollars. Nominal U.S. Treasury bonds, floating rate bonds and STRIPS are excluded.
