Néridia, a network operator, is testing the cash-generating unit of its regional fixed network at 31 December 20X1. The budget approved by management includes a fibre upgrade programme, not yet started, that would cost 40,000,000 and sharply increase revenue per subscriber. Without this programme, value in use would be below the carrying amount; with it, value in use exceeds it. The budget also provides for the regular replacement of the network's active equipment, whose useful life is shorter than that of the infrastructure. The finance director argues that, since the budget is approved, all its lines must be used. Write a judgement memo on how the cash flows should be built.
