The sub-fund will take proportionate exposure on the components of the SBI ESG Foreign AAA-BBB 5-10 Index (Total Return) using a stratified approach (stratified sampling strategy) by investing in a representative sample of components of the index selected by the portfolio manager using a 'portfolio optimisation' technique. The proportionate exposure by the Fund to the component securities will be substantially achieved either through direct investment or through the use of derivatives or through a combination of both techniques.
