The investment policy of the Fund is to track the performance of the Barclays Capital U.S. Treasury Index (or any other index determined by the Directors from time to time to track substantially the same market as the Barclays Capital U.S. Treasury Index and which is considered by the Directors to be an appropriate index for the Fund to track, in accordance with the Prospectus) (the “Index”) as closely as possible, while seeking to minimise as far as possible the tracking error between the Fund’s performance and that of the Index. The Index measures the performance of the US government bond market and includes public obligations of the U.S. Treasury. Certain special issues, such as state and local government series bonds (SLGs), as well as U.S. Treasury TIPS, are excluded. STRIPS are excluded from the index because their inclusion would result in double-counting. Securities must be rated investment grade, as defined by the Barclays Capital Index Methodology.
