Methodology Change | Solactive China AI Big Tech Top 2+ | Effective Date Latest 30/04/2026

Rationale for Methodology Change

Changing the rebalancing frequency from annual to semi-annual ensures the index more accurately captures the fast-evolving and volatile nature of the Chinese AI equity market. The introduction of a semi-annual weight reset day where the same weight scheme as the rebalance is applied to the current composition further mitigates the volatility of the Chinese AI Industry.

Changes to the Index Guideline

1.1 Scope of the Index

From: Rebalancing Frequency: Annually

To: Rebalancing Frequency: Semi-annually

3.1 Ordinary Rebalance

To:
Moreover, on each WEIGHT RESET DETERMINATION DAY the top INDEX COMPONENT per index category by ARTIS rank determined on the previous SELECTION DAY receives a fixed weight of 25%. To mitigate excess turnover, the following buffer rule is implemented, the top INDEX COMPONENT in each index category continues to receive the fixed 25% weight so long as it remains within the top five securities of that category by ARTIS rank as of the previous SELECTION DAY.

The remaining INDEX COMPONENTS are weighted based on their TOTAL MARKET CAPITALIZATION, with a weight cap of 5% by re-distributing any weight proportionally in an iterative manner, so that the total index weight sums to 100%.
