Highlights – 1Q18

381) New accounting standard in force since January 2018, which requires revenue to be recognized based on the contract with the customer, not necessarilyaligned with billing. For Vivo, revenue recognition of mobile offers with handset subsidy will change, as the subsidy will now be distributed between servicesand handset. In addition, certain costs to acquire a customer through a contract will now have to be capitalized if the amortization period is >12 months.

IFRS 15: new accounting standard in force since January 2018, which requires revenue to be recognized based on the contract with the customer, not necessarily aligned with billing. For Vivo, revenue recognition of mobile offers with handset subsidy will change, as the subsidy will now be distributed between services and handset. In addition, certain costs to acquire a customer through a contract will now have to be capitalized if the amortization period is >12 months.
