The investment policy of the portfolio shall be to track the SA Property Income Index (a custom index calculated independently by the S&P Dow Jones Indices) as closely as possible, by buying only constituent securities in the same weightings in which they are included in the Index and selling only securities which are excluded from the Index from time to time as a result of quarterly Index reviews or corporate actions. The SA Property Income Index is designed to measure the performance of large South African Listed Property Companies with an emphasis towards higher yielding companies.
