To reach this objective, the Sub-Fund will invest in securities sampled from the Index which may lead to an increase of the tracking error.Within the framework of this two-tiered sampling method, the Investment Manager will use the following approaches:- A portfolio optimisation carried out by matching modified duration both in terms of maturity and of geographical allocation;- A bond picking process aiming to select the best bonds in term of relative value.
