The investment objective of the Sub-Fund is to track both the upward and the downward evolution of the Morningstar US Large-Mid Cap NR Index (the "Index") denominated in US Dollars and representative of the United States’ large and mid cap equity market - while minimizing the volatility of the difference between the return of the Sub-Fund and the return of the Index (the “Tracking Error”). For daily hedged share classes, the Sub-Fund will also use a daily currency-hedge strategy, in order to minimize the impact of the evolution of each respective share class currency against currencies of each Index component. The anticipated level of the tracking error under normal market conditions is expected to be up to 0.50%.
