The composition of the Portfolio will be compared to the composition of the Index on a daily basis, taking into account any new investment contributions or withdrawals to and from the Portfolio, the receipt of any coupon payments for reinvestment, the effect of any corporate actions and its impact on the composition of the Portfolio relative to that of the Index. A tracking error minimising algorithm is used to determine the least number of transactions required to keep the Portfolio's returns aligned as closely as practically possible to the Index's returns while at the same time keeping the trading costs in the Portfolio to a minimum. The tracking error will never exceed 2% (two percent) on an annual basis. All cash movements and instrument events are taken into account daily in order to re-align the Portfolio to match the returns of the Index as closely as practically possible. The portfolio will invest in assets in liquid form, and in high yielding non-equity securities and interest bearing securities including but not limited to public, parastatel, municipal and corporate bonds, inflation linked bonds, loan stock, debentures, fixed deposits and money market instruments. When investing in derivatives, the Manager will adhere to prevailing derivative regulations. The portfolio manager will invest in derivatives for cash flow management purposes, as this is more cost effective, and to enable the investment manager to achieve the objective of tracking the Index more effectively.
