The Fund seeks to track the investment results of the MSCI Belgium IMI 25-50 Index , which is a free float-adjusted market capitalization-weighted index that is designed to measure the performance of the large-, mid- and small-capitalization segments of the equity market in Belgium. 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 Belgium Index. The Underlying Index uses a capping methodology that limits the weight of any single group entity to a maximum of 25 percent of the Underlying Index weight, and the sum of all group entities with a weight above 5 percent to an aggregate of 50 percent 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. To determine group entities, MSCI analyzes financial accounts of listed companies holding stakes of 20 percent or more in other listed companies to determine whether these stakes are controlling in nature. In certain cases, even in the absence of consolidated accounts, MSCI may also consider two companies as belonging to the same group entity where there is reasonable evidence of control based on other information. All group entities are reviewed on an annual basis.
