Index consultations procedure

Index consultations

Euronext Indices is committed to provide indices that respond to the best of its abilty to the needs of all stakeholders of its indices. In order to achieve this and in response to developments on the markets frequent feedback is sought among the known users of the indices. For major changes Euronext Indices will launch consultations from time to time via this page.

Each consultation will be open for at least 3 weeks.

A summary of the comments received will be published within 3 weeks after the consultation is closed. In principle the comments will be made public anonymously, indicating only the nature of person or institution providing the comment.

Taking into account the feedback received in the consultation, the Administrator will formulate a proposal for a rule change to the appropriate oversight committee for approval. As a rule such decision will be taken within 3 months after the decision.

In addition there are further changes proposed in order to align the Index methodology with the ESMA guidelines on funds’ names using ESG or sustainability-related terms. Specifically int concerns the following two changes: 

  • Exclusion of companies that derive more than 10% of their turnover from fossil fuel.
  • Exclusion of companies that derive more than 50% of their turnover from fossil fuel power generation 

Furthermore in order to simplify the weighting methodology it is proposed to change towards an optimization method instead of the current iterative approach.  

If approved by the Independent Supervisor the changes to the methodology will become effective as of the March Review of the Index.
