If the terms and conditions of an index-linked deposit contract allow the institution to make any changes in respect of the determination of interest payable to a person under the contract, the institution must disclose any of those changes that is a material change before making it — or, if that is not possible, as soon as possible after making the change — by describing it clearly, in plain language, in a written statement delivered to the person.
Si le contrat de dépôt indiciel permet à l'institution de modifier le mode de calcul de l'intérêt à payer, celle-ci doit communiquer toute modification importante à l'intéressé au moyen d'un avis rédigé en langage clair, avant la modification ou, en cas d'impossibilité, dès que possible après la modification.
