(Telecompaper) Telecom Italia (TIM) reported a 0.4 percent year-on-year decline in second quarter revenues to EUR 4.5 billion on a comparable basis, an improvement on falls of 2.5 percent and 2.9 percent in the previous two quarters, helped by a 2.4 percent rise in service revenues at its TIM Brasil unit that partly offset a 1.2 percent decrease at its domestic unit. The company's EBITDA was EUR 1.9 billion in the second quarter, down 2.6 percent on an organic basis, though the margin inched up 0.6 percentage points to 42.2 percent thanks to cost containment initiatives.
