Rationale for methodology change

Taking into account the feedback received from the Market Consultation, Solactive has determined to update the current capping constraint by applying a unique cap of 12% to the top 3 ranked securities and a cap of 4.5% for all the remaining index components. Additionally, the index will have a monthly re-weighting mechanism and change its ordinary rebalance schedule from semi-annual to quarterly.

This approach ensures that there is more flexibility to comply with the local Korean ETF Regulation where securities with individual weights below 5% can collectively account for more than 50% of the portfolio. Specifically, Article 80, Section 3-2, Point (b) of the relevant regulation states that “at least 50% of the total assets of the collective investment scheme shall be invested in securities issued by other corporations, with no more than 5% of the total assets invested in each security.”

In addition, if the INDEX ADMINISTRATOR determines that the INDEX weight of any INDEX COMPONENT is greater than 25% on any REVIEW DAY, then a weight cap is applied for each INDEX COMPONENT by re-distributing any weight which is larger than 20% to the other INDEX COMPONENTS proportionally in an iterative manner.

In addition, the Index will be re-weighted as per Section 2.3 on each REWEIGHTING DAY based on the weights calculated on the Review Day. If the total number of index components on the Review Day are less than 18, a new index composition will be determined as per Section 2.1 and 2.2.
