Dear Cboe Europe Participants,

Following the notice published by the Swiss Federal Council, as from 1st January 2019, a recognition obligation has been applicable to foreign trading venues if they admit shares of Swiss registered companies to trading or permit trading in such shares. In the event that Switzerland is not granted equivalence from the EU by Sunday 30th June 2019, Cboe Europe (Cboe) will not be permitted to admit to trading securities with a Swiss registered office and listed on a Swiss exchange with effect from the start of trading on Monday 1st July 2019. Please note that this applies only to shares (ETFs, ETCs, ETNs are not impacted).

In practice, this means that all On-Exchange activity (Order Books, Periodic Auctions, Cboe LIS, ETRs) in the affected instruments, will be rejected by Cboe. Please note that the submission of OTC trade reports or SI quotes to the APA (TRF) or SI platforms are unaffected and will continue to be permitted.
