24. SEGMENT INFORMATION The Company uses operating segment information for decision-making. The Company identified only one operating segment that corresponds to the telecommunications business in Brazil. In addition to the telecommunications business in Brazil, the Company conducts other businesses that individually or in aggregate do not meet any of the quantitative indicators that would require their disclosure as reportable business segments. These businesses refer basically to the following companies: Companhia Santomense de Telecomunicacoes, Listas Telefonicas de Mocambique, ELTA  Empresa de Listas Telefonicas de Angola, and Timor Telecom, which provide fixed and mobile telecommunications services and publish telephone directories, and which have been consolidated since May 2014. The revenue generation is assessed by the Company based on a view segmented by customer, into the following categories:  Residential Services, focused on the sale of fixed telephony services, including voice services, data communication services (broadband), and pay TV;  Personal Mobility, focused on the sale of mobile telephony services to subscription and prepaid customers, and mobile broadband customers; and  SMEs/Corporate, which includes corporate solutions offered to small, medium-sized, and large corporate customers. No single customer represent more than 10% of revenues neither 10% of receivables.
