The fund aims to track the performance of Bloomberg Euro Treasury Green Bond Tilted Index, and to minimize the tracking error between the net asset value of the sub-fund and the performance of the Index. The Bloomberg Euro Treasury Green Bond Tilted Index is based on the Euro Treasury 50bn Bond Index, and measures the performance of investment grade, EUR-denominated, fixed-rate government debt. The Index is tilted such that, on a rebalancing date, at least 30% of the Index's market value is allocated to securities classified as Green Bonds.
