In this regard, the Company was notified yesterday of the resolution issued by the Lower Commercial Court No. 9, Secretary No. 17 in the above referenced proceedings, which resolved to partially admit the claim filed by the “Unión de Usuarios y Consumidores” and “Consumidores Libres Cooperativa Ltda. De Provisión de Servicios de Acción Comunitaria” and ordered the Company to reimburse its customers for increases included in the invoices due in September 2018, corresponding to certain products provided under the brand Cablevisión. The court’s resolution also rejected the claimants’ request to declare null the clauses and conditions that provide for 30 days’ notice for rate increases..

Sincerely,
