(Telecompaper) AT&T has raised its target for free cash flow this year, supported by better working capital management, after reporting a record amount of USD 8.8 billion in the second quarter. Net earnings fell to USD 0.51 per share in Q2 from USD 0.81 a year earlier and also declined on an adjusted basis, due to a number of one-time items. The US operator said it still expects a low single-digit rise in full-year adjusted earnings.
