Fund seeks to track the investment results of the MSCI South Africa 25/50 Index (the Underlying Index), which is a free float-adjusted market capitalization-weighted index that is designed to measure the performance of the large- and mid-capitalization segments of the equity market in South Africa. The Underlying Index is rebalanced quarterly using an optimization process that aims to minimize the constituent weight differences between the Underlying Index and the MSCI South Africa Index (the Parent Index). The Underlying Index uses a capping methodology that limits the weight of any single group entity (constituents that MSCI determines have a control relationship) to a maximum of 25% of the Underlying Index weight, and the sum of all group entities with a weight above 5% to an aggregate of 50% of the Underlying Index weight. A group entity is a group of companies that operate as an affiliated corporate group but may separately issue listed securities.
