Bahrain domiciled CIUs must give at least one months' written notice to CIU participants of their intention to wind-up the CIU, together with an explanation for wishing to do so, and the options available to CIU participants (such options to include, if possible, a right to switch without charge into another CIU). A copy of this notice must be provided to the CBB at the time it is issued to CIU participants.
