Covered Sukuks are Sukuks issued by a bank or mortgage institutions and are subject by law to special public supervision designed to protect Sukuk-holders. Proceeds deriving from the issue of these Sukuks must be invested in conformity with the law in assets which, during the whole period of the validity of the Sukuks, are capable of covering claims attached to the Sukuks and which, in the event of the failure of the issuer, would be used on a priority basis for the reimbursement of the principal and payment of the accrued profit.
