Idorsia has mandated areg.ch to administer its Share Register. Investors wishing to register their shares are kindly asked to contact their prime custodian (e.g. your banker or broker) to request a share registration form. After completing the form, your custodian will send it to areg.ch who will then take care of the registration. The custodian will receive a confirmation directly from areg.ch once the registration has taken place.
