Swiss notification requirements
Under the SIX Swiss Exchange Act we disclose shareholders that reach, exceed or fall below the thresholds of 3%, 5%, 10%, 15%, 20%, 25%, 33.33%, 50% or 66.66% of the voting rights.
An additional disclosure requirement exists under the Swiss Federal Code of Obligations to disclose shareholders and their shareholdings if they hold more than 3% of all voting rights. This must be made once a year in the annual report.
